The thickness of the leather body of the welding gloves should be very uniform, the leather and fluff on the top should be relatively thin, uniform and firm, the color should be consistent, and there should be no different shades. If it is a glove, the glove should not feel greasy. The leather of second-class gloves may not be full and elastic. The fluff on the leather surface may be thick and the color may be very fine. The depth is slightly different.
The performance of welding gloves should also comply with the regulations of relevant agencies. The leather used for the palm and back of the hand should be relatively soft, strong and fairly uniform in thickness, while the leather used for the sleeves should be slightly elastic. The performance of welding gloves must also meet the requirements of relevant agencies.
There should be curled lines on the palm and back of the hand, which should be made of leather; when laying stitches on it, there should be open and dark stitches: when using bright stitches, 3 ~ 4 stitches per centimeter; when using dark stitches, every Centimeter can sew 4-5 stitches; when sewing this kind of glove, the shape of the hand must be straight, the thread stitched on it must be relatively straight, the distance between the needle angles must be relatively symmetrical, and the tightness must be appropriate. If you find that the needle is broken, the needle is dropped continuously, or the edge is skipped, you should re-sew the glove on the defective part, or remove the defective part, and sew the needle again.
Structure of welding gloves: There should be clamps embedded in the joints of welding gloves. Striped leather should be chrome-plated cowhide or pigskin. The edge leather and reinforced country leather should be the same as the palm and back leather. The width of the reinforced lining is more than 15 mm, and the needle code of the welder’s glove: 3-4 needles per centimeter of bare thread; black thread has 4 to 5 needles per centimeter. The sewing of welder’s gloves: the hand shape should be correct, the seam should be straight, the stitch length should be symmetrical, and the elasticity should be moderate. If you find broken needles, continuous oil leakage or skipped stitches, please redo the stitches or delete the problematic stitches and sew again.
Size of welding gloves: The minimum size of the length and width of welding gloves should meet the requirements of Table 7-17.
Length (L1) refers to the distance from the tip of the finger to the back edge of the middle finger, that is, the distance from the tip of the glove to the crib.
Length (L2) refers to the distance from the tip of the finger to the trailing edge of the middle finger.
Length (L3) represents the length of the glove cover; width (c) refers to the distance from the bottom of the little finger to the base of the index finger.
In order to ensure that the dimensions measured from various welding gloves are comparable, the gloves should be leveled before measurement. For welders’ gloves with special shapes, the size should be negotiated between the supplier and the buyer. Welder’s glove suture line: The welder’s glove suture line is required to be uniform and free of scars, and the single-line strength should be greater than 22.54N/50cm.
