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.
For an assembly plant to be so productive materials must be on hand at all times. Every mustang begins with a truck; reels of raw steel weighing in at 30 tons a piece are delivered periodically. Now this raw steel is the moved to a machine that cuts i...
Welding is a very important job in today’s society. With new building designs, and bridges to every day metal products, welders are needed to do these tasks. Almost everything that you use every day has some sort of weld to it.

It works by three main ingredients. Electricity, filler metal, and a form of shielding from the air are very important (gowelding para 2). “Just like MIG welding, Flux Core welding works by feeding an electrode continously to the joint” (gowelding para 2).The first step is the welder squeezes the trigger and a spool of wire is fed to the joint into the arc. As soon as the electrode hits the metal it heats it up until the wire and weld area begin to fuse together. Once the puddle is made the Flux Core creates a shield from the air (gowelding para 2). The power supply is a constant voltage power supply. This means the welding machine uses a direct current just like MIG welding, as the same machine is used for both types of
Even though welding has been around for a long time, most of the best inventors were around during the 19th century and have changed the way thing are done today. During the 20th century, many technological advancements developed and have made welding easier because of the different types of welding that have been developed. Welding impacted the world during World War l, because during the war armaments that were going to be utilized were ordered in tremendous amounts. Therefore, welding has been around since the Iron Age and has let people build strong steel and powerful armament such as Weapons, tanks, and planes. Finally, welding has had many advancements, and will continue to do so in the future, because the world needs
Behind every product manufactured there are parts, fasteners, gloves, welds, holes that are drilled, and maybe a headache or two. These are all products that are sold and manufactured by the companies W.W. Grainger and Fastenal Company. Both of these companies are in the top ten in revenue for the industrial supply industry and I just so happen to work at one of them, that being Fastenal Co.
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
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 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
