Material Requirements for Welding Protective Gloves

Welding protective gloves can protect hands and wrists from molten metal droplets and short-term flames, prevent limited direct contact heat and conductive heat damage, block arc ultraviolet radiation and prevent mechanical damage such as electric shock.

The glove material has a minimum resistance to withstand 100V DC arc welding. Welding protection products should comply with AQ 6103-2007, EN 407, ISO 11393-1 or ANSI/ISEA 107-2010, etc.

1. Welding protective gloves are generally made of natural leather and various linings.

Outer Layer: It is usually made of natural leather such as cow split leather, cow head leather, pigskin, sheepskin, etc.
Inner Layer: There are several kinds of inner lining of welding gloves, such as thickened lining, pure cotton lining, composite cotton lining, denim lining, etc.

2. First-grade leather is uniform in thickness, plump, soft and elastic, and the velvet is fine, uniform, firm, consistent in color and non-greasy; secondary leather lacks fullness and elasticity, has thick velvet on the surface and is slightly darker in color.

3. The thickness of leather and canvas should comply with regulations.

4. Mechanical properties should comply with regulations. Leather for the palm and back of the hand should be soft, strong, and even in thickness. Leather for cuffs should be slightly stretchy.

5. Chemical properties should comply with regulations.

6. No metal parts should be connected between the exterior and interior materials of the gloves to prevent electrical conduction.

Welding protective gloves are divided into two types according to their performance.

Type A: Low flexibility (with higher other properties);
Type B: High flexibility (with lower other properties).

1. Structure:

The seams between the palm and back of the welding gloves should be lined with leather strips. Chrome-tanned cowhide or pigskin should be used for leather strips. The edge leather and reinforced lining leather should be the same leather as the palm and back of the hand. The width of the reinforced lining leather is more than 15mm.

2. Needle Code:

3 to 4 stitches per cm for open thread; 4 to 5 stitches per cm for dark thread.

3. Sewing:

The hand shape of the gloves should be correct, the sutures should be straight and flat, the stitches should be evenly spaced, and the tightness should be appropriate. If any broken needles, continuous missed stitches or skipped stitches are found, re-stitch or remove the defective stitches and re-sew.

4. Protective performance The minimum protective performance should comply with the requirements in the following table:

1. There should be a product mark near the glove cuff.

2. Welding gloves are put into paper bags or plastic bags in units of pairs, and each bag should be accompanied by a product certificate. Then put the paper bag or plastic bag into a hardpackaging box, and each box should be accompanied by product instructions.

3. The packaging box should be clean, strong, dry and suitable for long-distance transportation. There should be no mildew or oil stains.

4. The transportation and storage of welding gloves should be carried out in accordance with the regulations of GB4694 or ISO 2481.
