Description

technical field [0001] The present invention relates to the field of welding technology, and more specifically, relates to a hand-held laser welding device and a safe operation method thereof. Background technique [0002] Laser welding, as an advanced welding technology, has been widely used in electronics, automobiles and other industries in conjunction with automatic control systems. However, the existing laser automatic welding equipment usually has a large volume and a standardized welding head. For some small batch production or when the shape of the workpiece to be welded is not convenient for automatic welding, due to the special angle and height of some parts, some Even inside the cavity, traditional laser automatic welding equipment cannot perform welding operations, so traditional laser automatic welding equipment is difficult to meet the above-mentioned types of welding requirements due to its flexibility and versatility.

However, the existing laser automatic welding equipment usually has a large volume and a standardized welding head. For some small batch production or when the shape of the workpiece to be welded is not convenient for automatic welding, due to the special angle and height of some parts, some Even inside the cavity, traditional laser automatic welding equipment cannot perform welding operations, so traditional laser automatic welding equipment is difficult to meet the above-mentioned types of welding requirements due to its flexibility and versatility

[0003] In recent years, handheld welding devices have appeared. Although operators can use these welding devices to achieve basic welding functions, they are still lacking in terms of safety protection. When operators misuse or use the handheld welding devices improperly , or the temperature of the welding device is too high, there will be certain safety hazards, and it will also affect the accuracy and quality of workpiece welding

[0004] In addition, when manual welding is used, the welder needs to go through quite a long time of training to make the weld barely reach the qualified level, and it is difficult to ensure that the weld meets the requirements of beautiful and smooth

Especially in the welding process, because the thin plate welding is easy to burn through, the welding speed must be fast, and the welding torch is relatively heavy. However, due to the lack of good support of the welding torch during manual operation, the straightness and uniform speed of automatic welding cannot be achieved. Poor straightness of the rear weld seam leads to welding deviation, uneven width, or even burn-through

[0005] During the hand-held welding process, for the butt weld of two workpieces at a certain angle, and the outer corner connection weld formed by the splicing of two workpieces at a certain angle, the welding seams of these two parts cannot be welded because the welding torch of the hand-held welding is not supported. Welding, or the welding effect is not good, not only greatly affects the quality of the welded seam after welding, the welded seam cannot meet the standard of external beauty and internal solidity, but also when the quality of the weld seam is not good enough, it needs to be cut off and re-welded, which is a waste of time and money. Waste of material, low efficiency of welding work, affecting work progress
