What is the main difference between manual welding and double-sided shielded welding?

As far as welding direction is concerned, gas shielded welding is basically push welding, while covered electrode arc welding is pull welding!

Gas shielded welding has simple operation and high efficiency. Do not replace the covered electrode and knock the welding slag.

Covered electrode arc welding needs to swing, otherwise the weld width can not meet certain requirements, and gas shielded welding can adjust the current and voltage to a certain width!

In fact, it is mainly the difference between pull welding and push welding!

Manual welding and repair are process steps that require excellent operation skills and good tools; An inexperienced operator may have a reliability nightmare. When equipped with adequate tools and training, operators should be able to create reliable welding points. Manual surface mount welding is sometimes more challenging than through-hole welding because the pin spacing is smaller and the number of pins is larger. During maintenance, care must be taken not to overheat the printed circuit board; Otherwise, the plated through holes and pads are easy to be damaged.

The invention is suitable for welding various large steel structures of low-carbon steel and low-alloy high-strength steel. High welding productivity, good crack resistance, small welding deformation and wide deformation range, which can be used to weld thin and medium plates.
