What is the maximum welding pressure of a 10-20L Automatic Seam Welding Machine usually, and what is the impact on the quality of the weld?

During the welding process of the 10-20L Automatic Seam Welding Machine, applying appropriate pressure to the welding surface can make the welding material transition from an elastic state to a plastic state. This transition process can promote the mutual diffusion of molecules and squeeze out the residual air in the weld. Taking metal materials as an example, when the pressure reaches the appropriate range, the gap between metal atoms decreases, and the attraction between atoms increases, which significantly improves the sealing performance of the weld welded by the 10-20L Automatic Seam Welding Machine. If the pressure of the 10-20L Automatic Seam Welding Machine is insufficient during welding, the material cannot fully undergo plastic deformation, and the molecular diffusion is insufficient, air may remain in the weld, resulting in defects such as pores in the weld, thereby reducing the weld sealing performance of the product produced by the 10-20L Automatic Seam Welding Machine.

Appropriate welding pressure can ensure that the appearance of the weld welded by the 10-20L Automatic Seam Welding Machine is flat, smooth, and uniform in size. When the pressure is moderate, the weld width and excess height of the weld can be effectively controlled. For example, when the 10-20L Automatic Seam Welding Machine welds metal plates, appropriate pressure can make the weld metal spread evenly and form a regular weld shape. If the pressure of the 10-20L Automatic Seam Welding Machine is too high during welding, the weld width will become narrower, the excess height will decrease, and it may even cause the weldment to deform; while if the pressure is too low, the weld width will increase, the excess height will increase, the weld appearance will become rough, and the size will be uneven.

Welding pressure has a vital influence on the strength of the weld welded by the 10-20L Automatic Seam Welding Machine. Appropriate pressure helps to increase the contact area of ​​the welding surface and better combine the weld metal with the parent metal, thereby improving the strength of the weld welded by the 10-20L Automatic Seam Welding Machine. Taking the stainless steel barrel seam welder as an example, during the welding process, by applying appropriate pressure, the weld metal can be closely combined with the stainless steel parent material, enhancing the tensile strength and shear strength of the weld. When the 10-20L automatic seam welding machine is welding, if the welding pressure is not appropriate, such as too little pressure, the weld metal and the parent metal are not tightly bonded, and the weld is prone to cracks, lack of fusion and other defects, resulting in reduced strength of the weld welded by the 10-20L automatic seam welding machine; excessive pressure may cause excessive extrusion of the weld metal, resulting in stress concentration, which will also affect the strength of the weld welded by the 10-20L automatic seam welding machine.

Stable welding pressure is one of the key factors to ensure the smooth progress of the welding process of the 10-20L automatic seam welding machine. During the welding process of the 10-20L automatic seam welding machine, if the welding pressure is unstable, the quality of the weld will fluctuate. For example, a sudden increase in pressure may cause the weld metal to be over-extruded, resulting in poor weld formation; a sudden decrease in pressure may cause defects such as pores and slag inclusions in the weld.
