Problems solved by technology

At present, there is already a lighting device that uses LEDs on the handrail of the stairs. Since the lighting device is installed on the handrail and the combination of the two needs to overcome many technical problems, one of the technical problems is that the lighting device relies on a bracket welded in the handrail sleeve. Fixed, the welding of the bracket has become a difficult problem

Embodiment Construction

[0016] Such as figure 1 and figure 2 As shown, 1 is a stainless steel armrest tube, 2 is an "凵" shaped stainless steel bracket, and 3 is the welding point of an "凵" shaped stainless steel bracket 2 and a stainless steel armrest tube 1.

[0017] The welding method of the inner bracket of the LED lighting handrail is as follows:

[0018] The first step is to prepare the weldment and argon arc welding machine, stainless steel armrest tube 1, and "凵"-shaped stainless steel bracket 2;

[0019] In the second step, use a wire brush to clean the weldment, the stainless steel armrest tube 1, and the "凵"-shaped stainless steel bracket 2 before welding;

[0020] The third step is to put the "凵"-shaped stainless steel bracket 2 into the stainless steel armrest tube 1 from the oval light hole, and use tooling to precisely position it; perform welding, and strictly control the wind speed at the welding operation to avoid air holes;

[0021] The fourth step is to weld with an argon arc w...

Abstract

The invention relates to a welding method for a bracket in an LED illumination handrail, belonging to the field of pipe welding engineering of stainless steel pipes. In the method, the stainless steel U-shaped bracket is welded on the inner surface of a stainless steel casing handrail; the external edge of the bracket can not go beyond the diameter of a light pore; the method has the advantages of less welding face and high precision of the welding position; the welding is the difficulty requiring to be solved by utilizing the light pore welding; and a plurality of skills of argon arc welding, and the like are utilized to reach the requirements in the strength, the surface flatness and the technological beauty of the welded bracket.

Description

technical field [0001] The invention relates to the field of stainless steel pipe welding engineering, in particular to a welding method for welding stainless steel pipe inner wall brackets. Background technique [0002] With the rapid development of LED lighting technology, LED lighting has been widely used in public places, highways and other places that need lighting. At present, there is already a lighting device that uses LEDs on the handrail of the stairs. Since the lighting device is installed on the handrail and the combination of the two needs to overcome many technical problems, one of the technical problems is that the lighting device relies on a bracket welded in the handrail sleeve. Fixed, the welding of the bracket has also become a difficult problem. How to rely on the light hole on the handrail to weld the bracket on the inner surface of the handrail without affecting the placement of the lighting device is a technical problem requiring details.
