Stainless steel is classified into three classes which include; ferritic, martensitic and austenitic. This classification is centered on their crystal structures. The chromium content of these metals is about ten percent. The austenitic grades come with a carbon content that is low. The following steps act as a direction in stainless steel welding
Ensure safety as an initial step. Always take precaution of others and yourself since gases and fumes generally affect health while electrocution can also be hazardous. Take note of the instructions provided by the manufacturer and provide the staff with safety gadgets. Make sure that ventilation is ensured by keeping exhaust at arc, put on protective gear for body, ears and eyes. Be alert not to come in contact with naked 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 any of the following processes; Stick electrode welding process by which there is an electric arc between a base metal and metal electrode which generates heat that is needed in the bonding process. It is an inexpensive and efficient process due to slang coating and stub loss. Tig welding process is performed easily on various metals. The electric arc that generates heat is between the base metal and tungsten electrode. If necessary, a filler metal is added. The arc is shielded by an inert gas.
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.
