Frequently Asked Technical & Procurement Questions

In-depth engineering answers addressing installation, material longevity, magnetic fields, and custom fabrication.

How does a Keean magnetic angle fixture prevent arc blow during high-current MIG/TIG welding?

Arc blow occurs when magnetic flux lines deflect the electric welding arc. Keean magnetic angle fixtures utilize a shielded magnetic circuit architecture. By focusing the flux loop internally between the high-permeability pole shoes and the workpiece substrate, external stray magnetic fields are reduced to under 5 Gauss at a distance of 15 mm from the tool edge, guaranteeing arc stability and uniform weld bead formation.

What is the maximum continuous working temperature before permanent magnetic demagnetization occurs?

Standard Keean assemblies use N-grade NdFeB magnets rated for up to 80°C (176°F). For high-heat pre-weld or heavy preheating conditions, custom units utilize SH (150°C), UH (180°C), or Samarium Cobalt (SmCo, up to 300°C) alloys. Thermal insulation gaskets placed between the faceplate and magnetic core prevent direct conduction of localized arc heat into the permanent magnet core.

How do air gaps and surface coatings affect the holding force capacity?

Magnetic holding force declines exponentially with surface spacing. An air gap of 0.5 mm caused by paint, rust, mill scale, or heavy galvanization can reduce nominal holding force by 40% to 60%. We recommend calculating holding power with a minimum safety coefficient of 2.5:1 to 3:1 when specifying magnetic fixtures for untreated hot-rolled structural steel.

Can custom angles and mounting patterns be machined into OEM magnetic fixtures?

Yes. Our CNC machining facilities produce custom pole shoe profiles, including V-grooves for round pipe/tubing alignment, custom degree bevels (30°, 60°, 75°), and standardized M6/M8 mounting holes for automated fixture table integration. Detailed 2D/3D DWG/STEP CAD proposals are provided for customer approval prior to tooling.

What surface treatments are applied to protect fixtures against marine and chemical corrosion?

Standard outer shells receive hard-anodized aluminum or electroless nickel plating on steel components, tested up to 240 hours of neutral salt spray (ASTM B117). For coastal and offshore infrastructure, complete 316 stainless steel housings and hermetically laser-welded magnet cavities are available to satisfy ISO 12944 C5 environmental criteria.
