Welding - McGill University School of Computer Science
Welding is a fabriion process that joins materials, usually metals or thermoplastics, by causing coalescence. This is often done by melting the workpieces and adding a filler material to form a pool of molten material (the weld puddle) that cools to become a strong joint, but sometimes pressure is used in conjunction with heat, or by itself, to produce the weld.

Different types of welding and what they are used for
Bare wire MIG welding can be used to join thin pieces of metal together. Flux core MIG welding can be used outdoors because it does not require a flow meter or gas supply. MIG welding is usually the welding of choice for DIY enthusiasts and hobby welders who don’t have the money to spend on expensive equipment.

Welding Electrodes types • Most widely used electrodes are E6010, E6011, E6013, E7018, and E7024 • 6010 arc welding rods are most commonly used for welding root passes in pipe and even for the fill passes on pipelines • 6011 arc welding rods are the kissing
In structural welding, a backing plate may be attached to the back side of joint to stop the through-flow of molten metal. Conversely, in pipe welding, an opening between the two sides is usually left that way, allowing the welder to weld through to the back and leave a weld bead on the outside.
Strengthen A Trailer Frame With These DIY Building Tips …
Welding vs. Bolting It may be obvious, but the biggest stiffening effect for a trailer frame comes when it is welded rather than bolted — especially when reinforced with a few gussets. Bolting is nice for taking it apart, and it is easier to assele.

How to Plug Weld | Our Pastimes
Instead, a metal inert gas (MIG) welding torch is used to weld in a hole drilled into the top plate to melt the lower plate and fill the hole with filler metal to create a plug. Drill holes every 1/4 to 1/2 inch along the width of the top metal plate that you are welding with a drill fitted with a 7.5 mm drill bit.
Filler Metals for Welding Today’s (and Tomorrow’s) High …
It is used for the fill and cap passes, making it a significantly more efficient alternative to traditional stick welding. In addition, the ‘J’ designation ensures the wire has been stringently tested and offers results at -20 Fahrenheit lower than the specified temperature.
Tips For Avoiding Common Flux-Cored Problems & …
To prevent nesting—a tangle of wire that halts the wire from being fed—during FCAW welding, always use knurled V- or U-groove drive rolls in your wire feeder. Compared to a GMAW solid welding wire (which uses a smooth V-groove drive roll), FCAW wire is much softer (due to its tubular design) and if you use the incorrect drive roll, it can easily compress the wire.
SPOT WELDING TECHNICAL INFORMATION - Tite-Spot …
When MIG welding galvanized steel, the weld puddle is 2550 degrees F. It should be obvious, even to the causal observer, that if you put 2550 degree liquid steel over a galvanized coating that boils at 1350 degrees F. that a great deal of spatter will occur.

Complete Guide to Robotic Welding | Fairlawn Tool, Inc.
Robotic welding, also called automated welding, is the automated process of using mechanized programmable tools to weld and handle a part. This relatively new appliion of robotics has filled the gap left by the growing shortage of welding professionals, effectively taking over a large portion of welding jobs the North American industry.
4 Major Types Of Welding Electrode Coatings - …
2017/1/24· If the flux coating is placed inside a long tube, the electrode can be in the form of a bare wire in the form of a coil. Then the shielded arc process can be made continuous and automatic. The primary purpose of a light coating is to increase arc stability; the coating is also called as ionizing coatings.
Welding | Metallurgy for Dummies
A related process, flux-cored arc welding (FCAW), uses similar equipment but uses wire consisting of a steel electrode surrounding a powder fill material. This cored wire is more expensive than the standard solid wire and can generate fumes and/or slag, but it permits even higher welding speed and greater metal penetration.
7 Most Common Welding Defects, Causes, and Remedies …
Overlap welding defect can be avoided by employing the correct welding Technique, using small Welding electrode and less welding has. Conclusion While welding defects and discontinuities may arise due to the welder’s poor welding skills, however, even the most skilled and experienced welders may in one way or another experience weld defects.
Press braking / brake forming process
Brake forming can commonly form metals up to 10" thick and some machinery will form pieces as long as 20 feet. The press braking process can produce a variety of shapes. Some of the most common shapes appear, two-dimensionally, in the table
Steel - Wikipedia
Steel is an alloy of iron with typically a few percent of carbon to improve its strength and fracture resistance compared to iron. Many other additional elements may be present or added. Stainless steels that are corrosion and oxidation resistant need typically an additional 11% chromium..

If you plan to produce several pieces, create your jig out of steel and you can weld right on it without fear of lighting it on fire. 5: Start with large pieces for the mount points. We used 2-inch lengths of 1.75-inch .120 wall aluminum tube.

Pressure may also be employed. • Since a slight gap usually exists between the edges of the work pieces, a ''filler metal’ is used to supply additional material to fill the gap. But, welding can also be carried out without the use of filler metal.
One important technique for tig welding stainless steel is to get the puddle started quickly and to get moving quickly before too much heat builds up. Because stainless steel is not very thermally conductive, heat does not dissipate quickly and its easy to overheat.
