What do you know about laser welding machines for stainless steel tubes?

Automatic laser welding machine, can easily achieve a variety of angles, a variety of positions of welding, stacking welding, seam welding. Especially in the welding of thin stainless steel, iron, aluminium and other metal materials, it has the characteristics of fast welding speed, good surface effect, large melting depth and small heat affected area.

In combination with tooling fixtures and automatic programming control, it can realise the need for fast and consistent welding of similar products in large quantities. The automated laser welding machine is capable of carrying out small electrical welding operations.


The laser beam is focused to give a small spot and can be precisely positioned for use in mass automated manufacturing of micro, small and medium-sized product components.

Advantages of automated laser welding machines.

(1) The heat input can be reduced to the minimum required, the heat affected zone has a small range of metallurgical changes and the deformation caused by heat transfer is also minimal.
(2) The welding process parameters for single-pass welding of 32 mm plate thicknesses have been checked and approved, reducing the time required for welding of thick plates and even eliminating the use of filler metal.
(3) No electrodes are required, so there is no concern about electrode contamination or damage. (3) No electrodes are used, no electrode contamination or damage.
(4) The laser beam is easily focused, aligned and guided by optical instruments and can be placed at an appropriate distance from the workpiece and can be redirected between machines or obstacles around the workpiece, whereas other welding methods cannot be used due to the above-mentioned space constraints.
(5) The workpiece can be placed in an enclosed space (under vacuum or with a controlled internal gas environment).
(6) The laser beam can be focused on a small area, allowing small, closely spaced parts to be welded.
(7) The wide range of materials that can be welded and the ability to join various heterogeneous materials to each other.
(8) High speed welding can be easily automated and can be digitally or computer controlled.
(9) The welding of thin or fine wire does not cause reflow problems like arc welding.
(10) It is not affected by magnetic fields (as is the case with arc welding and electron beam welding) and can be precisely aligned with the welded part.
(11) The ability to weld two metals with different physical properties (e.g. different resistances).
(12) No vacuum and no X-ray protection required.
(13) A depth to width ratio of up to 10:1 if welding by perforation.
(14) The laser beam can be transferred to multiple workstations by switching devices.
