Ways On Stainless Steel Welding
There are three classes of metals based in stainless steel; Austenitic, martensitic and ferritic. Classification is based on their crystal s...

Ensure Safety first. Take caution in protecting yourself and others. Fumes and gases affect health and electric shock kills. Read manufacturers instructions and provide articles on workers safety to your employees, protect your head from the fumes . Ensure ventilation and keep the exhaust at the arc, wear protective gears for the body, eyes and ears. Take caution not to touch live electrical wires.
Decide on which joint design you will use. This will ensures strength of welded steel. When connecting base metals, ensure strength, metal thickness, bonding position and how accessible the joints are. Joints are of five types; lap joint, edge joint, butt joint, cornet joint and t joint. They are arranged in different combinations to ensure a variety of welds. Make use of fixtures and jigs to secure pieces. When you are connecting, clamp metal sheet, joints and fillets when working.
Choose a welding process. For the stick electrode process, heat needed for welding is from the electric arc that is flanked by the metal at the base and the metal electrode. It is a cheaper process but it is inefficient because of the slang coating or stub loss. Tig welding process can be performed on various metals. Heat used in the welding process is generated at an electric arc between base meal and the tungsten electrode. Filler metal can be added if necessary. An inert gas shields the arc.
Mig welding is quicker on metals of thin gauge and heavy plate. The arc between the base metal and filler electrode provides heat for the process. Shielding is by a gas. There are two types of Mig welding; the short circuit transfer and the spray transfer. Short circuit transfer is used in small, thin gauges and it produces shallower weld. In spray transfer method, continuous spraying of metal droplets is done to transfer metal on the arc.
Supposing the method of your choice need shielding gas, ensure that you have the best gas for use. The stick electrode requires no shielding gas. Use either helium alone or mix it with argon when working on thicker sections while helium is advisable for deep penetration.
When the metal pieces are the same, make use of a filler metal that has the same composition with the base metals so that the weld will have uniform properties. Consider the mechanical characteristics, probability of cracking and compatibility when choosing filler metal with different applications of the base metal.
Use either direct or alternating current when using the stick electrode method. Direct current takes one direction of flow in the circuit. It either uses straight polarity or reverse polarity. Its advantage is that it can work even in settings with low current. Use direct current having a straight polarity in Tig bonding.
