To address the common dressing quality issues, Qiaotian achieved stable dressing of standard spherical caps through shaping cutter design, material optimization, and process innovation. Tool life has been extended to 50,000–100,000 cycles, and the theoretical service life of a single pair of electrode caps can reach up to 20,000 weld spots (compared with only about 3,000 for cutting-type dressers). The solution also ensures a flat cap end face, reduces welding spatter, and guarantees weld nugget strength and appearance quality.
For OEM B's challenges, Qiaotian provided a customized solution: customized design ensures stable and reliable dressing of 18° large-angle special-shaped welding guns; a modular design enhances the axial load-bearing capacity, maintains balanced force distribution, and improves durability for single-sided welding with small throat depth; and legacy-brand swing-arm dressers were retrofitted by increasing the floating cylinder stroke and extending the guide rods and mounting backplate, eliminating swing interference and unreachable positions.
For OEM C's challenges, Qiaotian likewise provided a systematic customized solution: narrow-edge welding electrode cap dressing adopts a two-stage cutting design — the first stage cuts the side deformation melting point, and the second stage cuts the small convex surface, using the 13 mm electrode outer diameter as a guide, with an improved chip discharge port. The two-stage guide coordination ensures a stable and reliable dressing process. For the difficulty in adapting to small throat depth welding gun models, customized design meets their dressing requirements.
