High-speed plasmaarc cutting technology plasma engineering hot metal cutting, and partial melting with high flow will also be the molten metal blow, form a narrow incision.
The forces acted on melting pool during plasmaarc welding process are analyzed. The violent movement of liquid metal is as the result of joint forces acted on the pool.
