Want this question answered?
The Type of welding you are doing, the brightness of the arc.
It depends on what you are welding. If you are doing welding on mild steel go with MIG welding; if it is aluminum or stainless steel then use TIG welding. TIG welding gives a nice looking finish. If you just want to get a decent look, then MIG is preferable and easy.
Welding is done to weld materials by operating a welding machine. Many industries such as Shipyard, Robotics will be needing welding applications. The applications include extending a rod eor pipe, joining two materials etc. My brother is doing a welding course at Weldtech Training Inc at Ontario. He is very much fond of welding. It gives someones great opportunities to work in several fields.
Usually welding jobs require that you have a college degree. Most of the time they want you to get at least an Associate of Science in Welding. This shows that you know what you are doing and are commited to the job.
That can only be known by doing a soil test. Generally none. Some people swear by Epsom Salts
It depends on what you're doing ... welding or soldering, mixing drinks, cooking.
At least a #5.
yes doing it for 24 years now from Fiji living now in Melbourne Australia. Have got class 1 certificate for welding and fabrication been using 6 meter Guillotine.
metal active gas, doing gas metal arc welding with a gas that isn't inert
they talk to the plants by doing farts
while doing the welding ,the weld metal should be deposit in the weld pool of parent material and electrode.In some type of welding like TIG ,the electode is not consumable ,it is used to create arc betwenn the electode and the parent material.In such cases,the filler metal or wire is used to join the parent material
Depends on how thick the metal parts are, and how well the seams are prepped. You also need to consider the duty cycle of the welder if you're doing serial production or long welds.
