求翻译：电弧在气流压缩下燃烧，热量集中，周围气流对焊缝有冷却作用，因此焊接接头的热影响区小，焊后变形小，可对3mm以下薄板进行焊接。是什么意思？

Arc burning in the compression of air flow, heat concentrated airflow around a cooling effect on the weld heat affected zone of welded joints is small, small deformation after welding, welding of the sheet below 3mm.

An arc in the air stream compression, combustion, heat, air flow around the weld with a cooling effect, so the hot solder joints affected area is small, small, deformed after welding to the 3mm to the sheet metal welding.

The electric arc burns under the contraction of the flow, the quantity of heat is centralized, periphery the air current has the cooling effect to the welded joint, therefore the weld joint heat-affected zone is small, after welds distorts slightly, may the thin steel plate carry on the welding to 3

ARC in air compression combustion, heat set, has a cooling effect of airflow around the weld, heat-affected zone of welded joint of small, welding deformation of small, 3mm plate can be welded.
