1.0 Introduction
During the snow storm on March 12th, 2014, fabrication was underway at Walters Inc. in Hamilton, Ontario. Even though our tour took place indoors, the weather gave us an insight to what conditions the field crew would experience while erecting the structural steel. Walters Inc. designs, fabricates, and erects structural steel systems. The following sections will explain:
• Typical Procedure for Projects
• Welding Processes and Positions
• Torque Control Bolts and Making Holes in Beams
• Efficient & Economical Member Utilization
• Fitters and their Role in a Project
• Pricing and Drawings
2.0 Walters Project Procedure
There is a long process between the point that Walters is awarded the job and when steel arrives on site. After the bidding stage, Walters receives structural and architectural drawings from the client. They start by detailing the connections to suit the clients’ drawings. If any changes occur, or if a connection is too complex, they can meet with the client to discuss how they can make the connection less complex. This is all completed while keeping in mind the welding positions for the on and off site welders. Walters’ employees would then start making a timeline of when the steel pieces would be erected.
After the connection drawings are complete, they are sent for approval. If they are not approved, the drawings ar...

...anged innumerable times over the project's life. Continual rework and time delays had hampered progress. Bolger had reported design errors that necessitated the refitting of complex equipment and rework of the aluminum welding. Materials requirements included the use of welded aluminum. Bolger normally employed only steel welders; aluminum welders were in short supply and impatient during work stoppages. The Bolger contract was cost based plus a fixed fee. A particularly disturbing problem was Bolger's cost reporting system. Bolger contract negotiators waited for up to three weeks for cost data.

Friction stir welding is a solid state welding process; this remarkable up-gradation of friction welding was invented in 1991 in The Welding Institute [1]. Figure 1 shows the schematic representation of the Friction Stir Welding process. The process starts with clamping the plates to be welded to a backing plate, so that the plates do not fly away during the welding process. A rotating wear resistant tool is plunged on the interface between the plates to a predetermined depth and moved forward in the interface between the plates to form the weld. The external tool has a probe and shoulder which stirs the material to be joined and forges the surface. FSW comes together with forging and extrusion processes. The probe and shoulder extrudes the material by stirring and the shoulder alone forges the material surface to be joined.
What is welding some may ask. “Welding is the use of brazing or soldering to join together or split apart pieces of metal.” Says miller electric inc. The First recorded forms of welding was from the bronze age when metal boxes were made by “pressure welding lap joints together.” In medieval times welding was used by hammer to forge weapons of different types. “It was actually not until the late 1800’s that traditional welding
Welding started back in the medieval days. But there was only one welding process, and it was called forge welding. Forge welding is the use of heating metal, shaping it (by pounding it with a hammer), then cooling it. People back then had to go to their local black smith go get things fixed. Some tasks required black smiths to be extremely precise, and have an even level of thickness throughout the piece of metal that they are foraging.
Gas metal arc welding, or most commonly referred to as MIG welding is a very common and sometimes preferred method of welding. Gas metal arc is personally one of the easiest and controllable welding types there is.
Using manual welding, it is very tricky to achieve the utmost standards of quality and safety. This is mainly due to ce...
To make a decent weld, one has to have a steady hand, the proper safety equipment, and the welding tools must be set up to sometimes exacting specifications; unless you’re using explosives, then the specifications must always be exact.
Thomas Jefferson said, “I find that the harder I work, the less I call it work”. I have often found myself in situations where I needed to fix something but could not because it is metal. I believe this might be why I began to show interest in welding. There is great satisfaction in being able to create or fix a metal object on your own. As a Certified Welder, I will be able to combine my hardworking drive with my personal interest in metal working to be a successful welder. This paper will explore the job description, requirements, and salary expectation for a Certified Welder.
Another type of welding is”Tig welding” which is when a electrode such as aluminum or tungsten that is melted with a strong torch or electrical arc. Another type of welding is “Mig welding” that is when you have a spool of wire and a inert gas such as argon or Co2 which acts as an insulator for the arc that is created in order to weld a bead. There are many more types of welding that you can learn when you are studying to become a welder or fabricator. When studing for welding you can and will learn about so much more stuff like oxy torch cutting and flux core welding which i hope many people will have the ability to at least try welding

Welding is an art, science, and high paying career all in one. Welding is the most effective way to join two pieces of metal, it is the only way to join them so they act as one. Numerous things in our daily lives has been welded from coffeepots to skyscrapers. Welding can be done almost anywhere outdoors, indoors, underwater, and even space (“Welding Basics”). It is practically
