Soapstones (AKA soapstone markers or soapstone chalk) are markers used in welding and other fabrication operations to temporarily mark metal surfaces in order to make precise welds or cuts. Largely comprised of the mineral talc, welding soapstone markers are soft, highly heat resistant, and will not contaminate the weld. Also, their marks are easily removable once the weld is completed. Zoro supplies soapstones, soapstone marker sets and soapstone holders (to reduce breakage). For more welding accessories and supplies, see our welding tips, TIG torches, and
welding nozzles.
Frequently Asked Questions
Soapstone possesses excellent heat resistance, allowing it to withstand high temperatures without cracking or warping. Its low thermal conductivity prevents heat transfer, protecting work surfaces and tools from damage. Additionally, soapstone's non-porous, low-friction surface is perfect for forming, shaping, and soldering metals.
Soapstones are commonly used as welding tables, providing a stable and heat-resistant surface for welding operations. Their ability to absorb and retain heat ensures even distribution, preventing warpage or distortion of welded pieces. Additionally, soapstone can be shaped into custom fixtures for specific welding tasks, offering precise alignment and support.
Soapstone's low thermal conductivity and non-porous surface make it an ideal material for soldering. It prevents excessive heat transfer, ensuring precise control over the soldering temperature and minimizing the risk of damaging delicate components. Its smooth surface allows for easy flux removal and provides a clean soldering surface.
Soapstones serve as effective barriers against heat and sparks during brazing. Their heat resistance protects work surfaces and surrounding areas from thermal damage. Additionally, their non-combustible nature reduces the risk of fire hazards, enhancing safety in brazing environments.
