Welding is one of the most difficult trades and it takes time and of course welding tips to learn how to do it. Attention to detail and having a depth knowledge of all the factors that influence the quality of the final result are essential when it comes to this trade.
That is why it is so important to take theoretical lessons about the fundamentals of welding and training, and of course learn from experts if you want to start a career as a professional welder.
- Knowing the metal is essential.Good welders need to have some metallurgic knowledge, that is, they should know the type of base metal and the electrode they are welding with, to understand the behaviour of the final bead.
- Choosing the current.The type of metal, together with the type of electrode, has a direct influence on the current (AC/DC) welders should use to perform a welding bead. So, you need to review the theory and try to do some practice on scraps with different settings.
- Keep calm and relax your hand.Relaxing the hand, specially the wrist, instead of holding the gun or the stinger too tightly is crucial for a good welder to have control over the weld pool and perform a good weld.
- Striking the arc.Striking the arc can be so difficult for beginners. The best thing is to strike the arc exactly at the starting point of the welding bead. It is a common and big technical beginner’s mistake to do it outside the weld joint, on a table or on a piece of scrap.
- Removing slag.Another major mistake beginners make is not removing the slag from a weld correctly, causing some problems like: very brittle weld, and also the weld can be covered with slag, making it difficult to judge the consistency of the underlying welding bead.
- Keep it clean. Not cleaning or grinding the impurities (grease, rust, oil or rust) out of the weld joint can provoke a contamination of the weld.
