Toronto’s Guide to Structural Welding
by Weld Rich and Steel Inc


How many welding processes are there in the industry?

In addition to structural welding, there are seven welding processes in the industry, some of which have subcategories as well. The seventh category is a combination of various processes commonly used in the industry but not categorized on its own. Aside from that, there is also arc welding, solid state welding, resistance welding, brazing, oxy fuel gas welding, and soldering welding. Determining the process being used depends on the material, whether it is a repair, reinforcement, or new build, the purpose of the structure, and the environment the structure will be in. Weld Rich and Steel’s CWB certified welders work together with designers and engineers to determine the best solution for every project, and employ their skills and processes accordingly.


What are weld types?

Weld types are the methods employed to join two pieces of metal together along their surface. Determining which weld type to use depends on the material, the location of the joining, the type and direction or strain it has to endure, whether it is a repair, reinforcement, or new build, and the environment the structure will be in. There are four weld types that holds together two pieces of metal. The 4 weld types are the butt weld, fillet weld, edge weld, and spot weld. These weld types combine two metal surfaces together, usually overlapping. For connecting an edge to a surface or two edges, the welder would use a weld joint.


What are weld joints?

Weld joints combine a metal edge with a metal surface, or two metal edges together. The five types of weld joints are butt joint, tee joint, corner joint, edge joint, and lap joint. Weld joints can be prepared in a number of ways, including shearing, casting, forging, machining, stamping, filling, routing, cutting, and grinding. Determining which weld joint to use depends on the material, the location of the joint, the type and direction or strain it has to endure, the function of the joint, and the environment the structure will be in.


What is CWB?

The Canadian Welding Bureau (CWB) is an industry supported private sector not for profit organization, providing welder certification, management systems registration, and training services. Weld Rich and Steel welders are CWB certified and trained to ensure the highest quality and compliance to all codes.


Why is it important to work with CWB Certified welders?

The Canadian Welding Bureau (CWB) ensures that certified professionals adhere to safety codes as well as standards. Individuals must complete written and practical exams in order to be CWB certified. As the Authorized National Body (ANB) for the International Institute of Welding (IIW), the Canadian Welding Bureau (CWB) provides several levels of internationally recognized certifications and qualifications.


What kind of metal can be welded?

Any kind of metal used for your structural, construction, repair, or reinforcement project can be welded. Weld Rich and Steel works with you to see what metal and which processes will best fit your needs and your project. Varieties of metal that can be welded include -but are not limited to - mild steel, stainless steel, copper, nickel, titanium, and aluminum.


How do I choose what metals to use in my project?

Choosing the metal for your project largely depends on whether it is a repair, reinforcement, or new construction, as well as what conditions the structure will be withstanding after completion. Weld Rich and Steel consultants, designers, and engineers work with you to determine the best material and processes that fits your requirements, schedule, and budget.


What are the restrictions for welding?

Restrictions for welding could include confined spaces without proper ventilation, lack of or faulty personal protective equipment (PPE), or general unsafe worksites. Weld Rich and Steel professionals follow guidelines provided by the Occupational Health and Safety Act (OHSA) and make necessary adjustments to the workspace in order to maximize the safety of the personnel, as well as the quality of the project.


What do I need to prepare for a welding project?

Preparing a blueprint and shop drawings of your project helps give the consultants, designers, engineers, and technicians a great foundation to work from. Work out your budget ahead of time, and ensure you have a list of your requirements that must be met by the end of the project. If you need to work with a specific schedule or deadline, it should also be relayed to your collaborators. Having all this information early will mean no surprises along the way for either you or the professionals working with you, ensuring quality production within your budget and timeframe.


What are the abbreviations used in welding projects?

While you are going through blueprints and plans for your project with consultants, designers, engineers, and technicians, you may encounter many unfamiliar abbreviations. The below are the common terms and their abbreviations usually involved in the planning process.


  • WQT means Welder’s Qualification Test
  • WPS means Welding Procedure Specification
  • PQR means Procedure Qualification Record
  • GTAW means Gas Tungsten Arc Welding
  • SMAW means Shielded Metal Arc Welding
  • FCAW means Flux Cored Arc Welding
  • GMAW means Gas Metal Arc Welding
  • SAW mean Submerged Arc Welding


What is non-destructive testing (NDT)?

Non-destructive testing (NDT) examines the surface and subsurface of the weld and surround base material to determine quality and strength of the structure. Non-destructive testing (NDT) methods makes use of visual, liquid penetrant, magnetic particle, ultra-sonic, and radiographic (X-ray) information.


What are the non-destructive testing (NDT) methods for welding?

The five non-destructive testing (NDT) methods for welding are:


  • Ultrasonic testing
  • Magnetic particle testing
  • Penetrant testing
  • Radiographic testing
  • Eddy current testing


What kind of services are available from mobile welding in Toronto?

Weld Rich and Steel provides mobile welding in Toronto, coming to your facility or construction site for repair and reinforcement jobs. Services include crack-repairing, reinforcing, re-alignment, section replacements for equipment, systems, or structures. Professionals assess the situation and find the best solution for the highest quality repair or reinforcement, saving you the hassle and the money from buying new equipment.


What is structural welding and structural installation?

Structural welding is a part of steel fabrication and erecting welded structures. Examples of these are steel platforms, braces, and supporting structures. Structural welding would be the process of welding together parts that will become a part of an overall project. Structural installation is the process of putting together the project, like the supporting beams for a building, to become the finished product.


Why choose metal railings or metal stairs in Toronto?

Exterior metal railings and steel stairs in Toronto are sought after to withstand the drastic weather changes. The teething on metal stairs in Toronto are crucial for the city’s icy and windy winters, while the open treads allows for proper drainage of melting ice and reduces build-up of snow. Metal railings and metal stairs are useful in industrial or commercial facilities because they are durable and easy maintenance in the high traffic areas. Steel stairs are safer then concrete, and allows for more versatility in design.


Why is it popular to have metal railings and metal stairs inside the home?

Interior designers prefer steel stairs in Toronto to allow for light weight and fast construction, and can be finished with any material on the surface. Smaller living spaces have higher demands for steel stairs because aside from being light weight, the open treads also increase the flow of light. All the parts are accurately cut and produced offset, reducing installation time. In contrast, staircase installation of stone and concrete structures are never straight forward due to the irregularities of the material. High quality finish is often compromised because drilling stone on site has risks of cracking, entailing removal, remaking, and resetting


What is structural steel fabrication?

Weld Rich and Steel’s steel fabricators in Toronto craft products from scratch to completion for sheet fabrication, parts fabrication, or heavy fabrication projects. Structural steel fabricators might do heavy fabrication, including tow motor frames, sidewalls, and large tanks. Fabrication processes can include MIG and TIG welders, inner and outer shields or submerged arc welding manipulators, rolling beams, piping.


What does MIG and TIG mean?

MIG stands for Metal Inert Gas, and is a high deposition rate welding process. The wire is fed continuously from a spool. MIG is also sometimes known as semi-automatic welding. TIG stands for Gas Tungsten Arc, and is a process where an arc is formed between the metal and a tungsten electrode. TIG is used for high quality and precision welding.
