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
First ensure safety. Ensure self-protection and protect the others. Fumes and the gases used affect health and electric shock is dangerous. Read manufacturers guidelines and educate workers on their safety, Protect head form fumes. Ventilate the area and keep exhaust in the arc, Put on protective gears and avoid touching live 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.
There are many processes that you can choose from when working on the steel. One of them is the stick electrode which has an electric arc that is between metal base and metallic electrode that produces heat required in bonding. This process is both cheap though inefficient due to coating of slang and loss of stub. The tig process is easily performed on many metals. The arc that produces heat lies between the metallic base and the tungsten electrode and it is protected by inert gases. A filler metal may be added in case it is deemed necessary.
Welding of mig is faster on thin metal gauge and weighty plates. The process is provided with heat by the arc sandwiched by filler electrode and base metal. The gas doses the shielding. Mig welding come in two types; spray transfer and short circuit transfer. The short circuit is used in tiny gauges and produces shallow weld. The method of spray transfer continuously sprays metal droplets is undertaken to transfer the metal to the arc.
If the method you have chosen requires a shielding gas, determine the best gas to use. No shielding gas is required in stick electrode method. In tig process, use argon for thicknesses approximated to be half. On thicker sections, use a mixture of argon and helium or helium alone. For deeper penetration, employ helium.
When the pieces of metals are equal, use filler metal which has even composition with base metal in order to ensure that the weld gets properties that are uniform. Put consideration on mechanical characteristic, compatibility and the probability of cracking when finding out filler metal with varying applications of base metal.
Make use of direct or an alternating current when using stick electrode method. The direct current has a one direction of flow. It makes use of straight polarity or a reverse polarity. It has an advantage as it works in settings of a low current. Use a direct current with a straight polarity.
