MIG welding is one of the most popular welding techniques being used today. It can be used to weld a variety of metals and is one of the most in demand welding skills around. Because of its versatility, MIG welding has become a favorite among welders and manufacturers. Below we are going to offer you some tips to help your MIG welding processes be a success.
When a welder is using MIG welding to join two pieces of metal it is imperative that the joint be prepared correctly. MIG welding requires that the welding joint be free of oil, dirt, paint, rust or any other debris that can affect the quality of the weld. The best way to ensure that your welding joint is as clean as possible is to use a wire brush or grinder to get the weld area down to bare metal. If your joint isn’t clean, the quality of your weld will suffer.
Performing a successful MIG weld also requires that your welding machine is properly set up. MIG welding is a semi-automatic welding process that requires the welder to have the proper knowledge to correctly set up their machine. A welder is required to determine the proper amount of voltage needed to create the desired weld. Welders also need to know the correct wire feed speed to use for each type of weld they are performing. If your feed speed is too high or too low, your weld will be insufficient and may have defects present that will affect the integrity of the weld. Welders will also need to know the correct shielding gas flow rate to use for each type of weld. The shielding gas flow rate should be at a level that the weld is protected from any surrounding air and remains free of contaminants during the welding process.
The welding techniques required in MIG welding are similar to those used in other welding processes. Some welders prefer to use a whipping technique when they are welding, which consists of welding in a back and forth motion. Other welders prefer to use circles or a side to side weave technique. Whichever welding technique you decide to use it is important for the success of your weld that the wire stick-out should never exceed 3/4 of an inch. If your wire stick-out is more than 3/4 of an inch, the shielding gas will not be able to properly do its job.
These are just a few tips to help your MIG welding process be more productive. MIG welding is a highly popular welding technique and with some time and practice it is a welding skill that can be mastered by every welder.
