Manual welding thick-walled steel pipe

Welding method of thick-walled steel pipe is the most commonly used manual welding, manual welding: manual welding is a very common, easy to use welding methods arc length is adjusted by human hands, it depends on the gap between the electrodes and the workpiece the size of the same time, when the carrier as the arc when welding the weld filler material also.

This welding thick-walled steel pipe method is very simple and can be used to weld almost all materials for outdoor use, it has good adaptability, even in the underwater use have no problem. Most welders can TIG welding electrode welding , the arc length determined by the human hand: when you change the gap electrode and the workpiece, you have to change the length of the arc, in most cases, welding using direct current, the arc electrode both as carrier and also as filler weld material from the alloy or non-alloy electrode metal core wire and the electrode coating composition of this layer of coating to protect the weld from air violations, while stabilizing the arc it also caused the formation of slag layer to protect the weld it shape. welding bars to titanium type electrode, but also seal in nature, depending on the coating thickness and composition. titanium rod easy to weld, weld flat appearance. Additionally, welding slag is easy to remove if the rod storage for a long time, must be re-baked roast because moisture from the air will quickly accumulate in the electrode, so says manual welding thick steel is the most commonly used method.
