What are the technical requirements for welding gloves?

Welding gloves are special protection gloves for welding workers. They are one of the special protective articles. The gloves are fire-resistant and heat-insulating, which can prevent the high temperature, molten metal and splash sparks in the welding process from harming the workers' hands. The welder's gloves are usually made of pigskin, cowhide, sheepskin, etc., which is made into finger-type or two-finger gloves. The overall length of the cuff is generally greater than 18 cm and the material is generally canvas or leather.
The quality of the welder's glove product should conform to the LD34.3-92 standard.

1. The welding gloves should be made of wear-resistant, radiant heat-resistant leather or cotton canvas and leather composite materials. The length of the welding gloves should not be less than 300 mm. To sew, the welders should not wear worn or wet gloves.

2. When the welder is working in a welding place that may be conductive, the welding gloves used should be made of a material (or an additional insulating layer) that has insulating properties and can be used only after passing a 5000V withstand voltage test.

3. Welding gloves material requirements

3.1 Appearance: The first grade leather body is uniform in thickness, full and soft and elastic, and the leather is fine, uniform, firm, and consistent in color and shade. No greasy feeling; lack of full elasticity of the second grade leather body, rough leather surface, a slight shade of color.

3.2 The thickness of leather and canvas should meet the requirements.

3.3 The mechanical properties should be in line with: The palm of the hand and the back of the hand should be soft, strong and uniform in thickness. Leather for sleeves should be slightly elastic.

4. Welding gloves production requirements

4.1 The seams on the palm of the welding glove and on the back of the hand should be clipped. Clips are to be made of chrome leather or pigskin. Skins and reinforcements should be made of the same leather as the palm and back of the hand. The width of the reinforced liner is 15mm or more;

4.2 needle yards 3 ~ 4 needles / cm; dark line 4 ~ 5 needles / cm;

4.3 Sewing: The shape of the hand should be positive, the suture should be straight, the stitch length should be even and the elastic should be moderate. If there is a broken needle, a continuous needle drop or a jump stitch, the needle should be doubled or the defective stitches must be removed to re-sewn.
