    How to Weld Steel Pipe to Stainless Steel Pipe successfully

    You needs methods to combine two pieces of dissimilar metals .Generally, TIG/MIG and stick welding are used for welding steel pipe to stainless steel pipe.The important thing is to choose electrodes which are good at the desired weld.As for MIG welding,it uses an E70 electrode. And a 7018 electrode is for sticking weld. In order for the weld to seal properly, a high-carbon stainless steel electrode must be used. The preferred electrode to use for jointing and being sealing is a 309 electrode. This electrode secure the good welding penetration and seals properly.Welding steel pipe to stainless steel pipe, you should start by cutting the end off of the welding wire that may be sticking out of the welding tip of the MIG welder.  This can be easily trimmed. Then you need to be back spool in order to remove the welding wire from the MIG gun and lead. Once you have the welding wire and removed it from the gun, you will need to load the welding gun with the 309 welding wire. Then your welding gun is loaded with the proper wire.The next step is to exchange the gas with the three part shielding gas mixture which is needed for this type of welding. Now your shielding gases have been properly attached. Because welding stainless steel requires a higher level of heat than carbon steel. You should begin your weld on the stainless steel pipe and pull the weld puddle onto the carbon steel pipe.   If you notice that the carbon steel pipe is under-cutting, you need to reduce the heat setting on your MIG welder and repeat the process.  If reducing the heat setting fails to improve the level of under-cutting taking place, you should speed up the stroke of your circle so that you can pull the heat away from the steel pipe.  Doing this should help rectify the under-cutting and leave you with a strong sturdy weld. Once the weld is completed you should check the entire surface to ensure there aren’t any defects or weak areas.  If you should happen to notice any defects you can go back and remove the weld and do it again.  With some experience you should be able to master this welding technique and your welds will improve each and every time.
