A method of using a welding helmet

Abstract

The invention belongs to the technical field of welding, and specifically relates to a welding operation method. The method uses a welding helmet, which includes a face shield, goggles, a breathing apparatus, a headgear, an elastic tube, and a suction pump. The face shield is a hard Materials, goggles are set at the front end of the mask, the goggles are fixed to observe the welding process, the breathing device is fixed at the front lower end of the mask, the headgear is set along the direction of the head circumference, the end of the headgear is fixedly connected with the mask, and the headgear is made of rubber. An elastic tube is arranged on the outside of the headgear, and the elastic tube is arranged along the head circumference direction. One end of the elastic tube is connected to one side of the face shield, and the other end of the elastic tube is connected to the other side of the face shield through a suction pump. The rubber headgear reduces the wear and tear of the helmet. Weight, easy to wear on the head for a long time, the elastic tube controls the air pressure in the tube through the suction pump to achieve the effect of shrinking the elastic tube, thereby adjusting the size of the headgear to meet users with different head circumferences, and improving the comfort and applicability of use.

Description

technical field [0001] The invention belongs to the field of welding technology, in particular to a method for using a welding helmet. Background technique [0002] Harmful ultraviolet and infrared radiation generated by the arc during the welding operation, as well as damage to the eyes caused by strong welding light; spatters and harmful substances that appear during the operation will cause damage to the face and skin burns; the welding operation cannot To effectively avoid these, we use welding masks to protect the workers and reduce the damage to the workers. However, the traditional welding masks need to be held by the workers, which limits the operating range of the workers and cannot meet the need for two-handed operation. Welding method. [0003] In the prior art, there are also some technical solutions for welding masks. For example, a Chinese patent with the application number: 201711179910.0 discloses a welding helmet, which includes: infrared image information ...

However, the traditional welding masks need to be held by the workers, which limits the operating range of the workers and cannot meet the need for two-handed operation. Welding method

[0003] In the prior art, there are also some technical solutions for welding masks. For example, a Chinese patent with the application number: 201711179910.0 discloses a welding helmet, which includes: infrared image information acquisition equipment, image processing equipment and auxiliary welding equipment, Adjustable AR display screen; infrared image information collection equipment installed on the upper part of the front of the helmet, used to collect the infrared shape and temperature field images of the molten pool of the metal weldment and its surroundings in real time, and send them to the image processing equipment; image processing The equipment is used to perform image processing such as image enhancement and image segmentation on the received infrared topography and temperature field images, extract and identify the defect features in the images by comparing with the expert database, and convert the processed welding area topography The image result integrated with the temperature field is output to the adjustable AR display screen. Although the helmet of this solution can be worn on the head of the operator, the size cannot be adjusted, and it cannot effectively fit the head of the operator, and cannot meet the needs of different head shapes.
