Gasless secondary welding is a common welding method that does not require additional gas protection, but uses a flux-cored wire to release carbon dioxide and other gases when burned, preventing oxidation of the welding metal. Let's take a look at the operation steps of gasless two-protection welding:
1.Prepare your tools: Make sure you have the necessary equipment such as a gasless welding machine, welding gun, power supply and shielding gas. At the same time, wipe the welded workpiece clean, find the correct position and fix it well, so as to ensure the stability of the welding process.
2.Adjust the parameters: Set the current, voltage and shielding gas flow of the welding machine according to the material, thickness and desired welding effect of the welded workpiece. These parameters have a great impact on the welding quality and should be adjusted according to the actual situation.
3.Start welding: Before welding, make sure that the welding gun and the workpiece are in good contact. Then press the trigger on the welding torch to start the welding current and start welding. During the process, the welding torch should be kept stable to prevent uneven welds or other problems.
4.Safe operation: When operating the airless welding machine, it is necessary to comply with safety regulations and wear protective equipment, such as welding masks, gloves and protective clothing, to prevent sparks, heat and ultraviolet rays.
5.Precautions: When welding with airless two shields, it is necessary to avoid common faults, such as the problem of wire threading, so as not to affect the quality and efficiency of welding.
6.Maintenance: After the welding is completed, clean up the equipment and maintain it to prolong the life of the welding machine and ensure the normal use of the next time.
With these in mind, you will learn the basic usage of gasless two-shield welding. But to improve your welding skills, you need to practice and gain experience. Come on!
