1results about How to "Does not affect welding quality" patented technology

The application relates to the field of welding technology, in particular to an automatic welding method and device applied to marine parts. The automatic welding device applied to the marine parts comprises a welding machine body and an auxiliary device; the auxiliary device comprises a supporting frame, a pay-off roll, a winding roll and a one-way assembly; a conductive belt is arranged between the pay-off roll and the winding roll; one end of the conductive belt is fixed on the pay-off roll and wound on the pay-off roll, and the other end of the conductive belt is fixed on the winding roll; in the process that the upper electrode is driven to move upwards to separate the conductive belt from the workpiece after welding, the one-way assembly prevents the pay-off roll from rotating, and the winding roll rotates to wind the conductive belt to tension the conductive belt between the pay-off roll and the winding roll, switch the contact position of the conductive belt and the next workpiece, and remove the adhered impurities, so that the subsequent welding is not affected.
