The invention relates to the field of explosive welding layered metal composite materials, and provides a dust-removing and environment-friendly explosive welding method which comprises the following steps: manufacturing a water-sand foundation: placing an explosive welding device on the water-sand foundation; laying a water bag and a detonating cord on the periphery of the explosive welding device, and finally detonating the explosive welding device and the detonating cord at the same time to complete explosive welding of the layered metal composite material. According to the dust-removing and environment-friendly explosive welding method, the water-sand foundation serves as the explosive foundation, dust formation during explosive welding can be reduced from the source, and the interface bonding performance of the layered metal composite material is improved; the water bags are distributed around the explosive welding device, the detonating cord is detonated to explode to cause atomization of the water bags, the water bags make contact with dust generated by explosive welding, and the effect of rapid dust removal is achieved. The two dust removal methods act together, operation is easy, the explosive distribution state does not need to be changed, and the welding quality is not affected; and the dust removal effect is also greatly improved.

The invention discloses a refrigerator steel plate box shell welding device, and relates to the technical field of refrigerator steel plate box shell welding, the refrigerator steel plate box shell welding device comprises a base and steel plate parts, the top of the base is provided with a right-angle frame, the two steel plate parts are placed on the right-angle frame, and a welding assembly for welding the two steel plate parts is arranged above the right-angle frame; supporting seats fixedly mounted on the base are arranged on the two sides of the right-angle frame, a mounting frame is fixedly mounted on the tops of the supporting seats, and a control assembly for stabilizing the steel plate piece is arranged on the mounting frame. According to the welding device for the refrigerator steel plate box shell, a second air cylinder drives a connecting plate, a pressing plate and other components to move synchronously, precise pushing of two to-be-welded steel plate pieces is achieved, it is guaranteed that the to-be-welded ends of the to-be-welded steel plate pieces can be tightly attached through the pushing action, a welding gap is effectively eliminated, and therefore the subsequent welding effect is guaranteed, and the welding efficiency is improved. By means of the design, the sealing performance and strength of welding are improved, and the service life of the welding structure is prolonged.

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.
