A plastic weld is only as good as the testing that verifies it. For structural, food-grade, chemical-handling, and waterproof-membrane applications, you must be able to prove the weld bond strength meets the engineering spec. Plastic Welding Tools supplies the testing equipment that fabricators, inspectors and quality-control teams use to verify their welds — and to spot defects before they become field failures.

The range covers four main testing approaches:

Tensile testing (Handy Tensionmeter) — measures the peel strength of a weld coupon, giving a kN reading you can compare against the parent-material strength. The standard test for landfill and roofing-membrane fabricators.
Spark testing (Techspan Spark Tester Kit) — passes a high-voltage probe over a completed weld with a conductive wire embedded; any pinhole or void in the weld discharges visibly. Used on tank linings and chemical fabrications where leak integrity matters.
Air-pressure testing (Pressure Test Device with Needle) — pressurises the double-track wedge weld of a membrane seam to confirm it has fused fully across both tracks. The industry-standard non-destructive test for roofing and pond liners.
Coupon cutting (Coupon Cutter) — cuts standard-size weld coupons from a test weld for tensile testing, so your quality records use repeatable sample geometry.

Testing equipment is supported in Australia with spare probes, replacement needles and re-calibration where applicable. If you’re building a QA process for a plastic welding job and need help choosing the right combination of equipment for your standard, get in touch.
