Problems solved by technology

The arc ignition of manual arc welding mainly uses contact arc ignition to ignite the arc, and the large short-circuit current will cause burns of some thinner workpieces and burnout of the welding rod, resulting in defects such as impurities and virtual welding in the weld.
[0003] At the same time, when manual arc welding is used, the success rate of arc ignition is not high. The tapping method and scratching method are often used to ignite the arc. When the arc is unskilled, it is easy to cause the welding rod to stick to the workpiece, which reduces the efficiency of arc ignition. Seriously, the electrode will heat up and melt, causing defects in the workpiece to be welded, and the arc is also easy to extinguish after ignition.

Abstract

The invention provides an arc striking control method and device. The arc striking control method is used for manual arc welding and comprises the steps of judging whether the current arc striking of manual arc welding is within the preset time or not; if not, carrying out arc striking of manual arc welding by the adoption of a first arc striking control mode; and if yes, carrying out arc striking of manual arc welding by the adoption of a second arc striking control mode. The arc striking control scheme disclosed by the invention can improve the arc striking success rate.

Description

technical field [0001] The present disclosure relates to the field of welding technology, in particular, to an arc striking control method and an arc striking control device. Background technique [0002] Welding, as a very common joining process, plays an important role in industrial production and manufacturing. Manual arc welding equipment has the characteristics of portability and flexible handling. Therefore, manual arc welding can be performed in any place with power supply, and is suitable for welding of various metal materials, various thicknesses, and various structural shapes. The arc ignition of manual arc welding mainly uses contact arc ignition to ignite the arc, and the large short-circuit current will cause burns of some thinner workpieces and burnout of the welding rod, resulting in defects such as impurities and virtual welding in the weld. . [0003] At the same time, when manual arc welding is used, the success rate of arc ignition is not high. The tappi...
