Welcome to the dedicated product page for premium calcium carbide for welding. As a vital industrial raw material, calcium carbide ($CaC_2$) plays an irreplaceable role in metal fabrication, cutting, and industrial engineering. When reacted with water, our top-grade calcium carbide generates highly pure acetylene gas, providing the intense, stable, and high-temperature flame required for professional oxy-acetylene welding.
Whether you are a global chemical distributor, a metal manufacturing facility, or a large-scale industrial procurement manager, our calcium carbide for welding is meticulously manufactured to meet and exceed your technical specifications. We provide a full range of particle sizes, including 25-50mm and 50-80mm, with an outstanding gas yield reaching up to 295-310 L/Kg, ensuring maximum efficiency and minimal residue for your operations.

Superior Gas Yield & Purity: Our chemical technical grade features low impurity levels (such as phosphine and hydrogen sulfide), resulting in a cleaner burn and safer acetylene generation.
Strict Quality Control: Every batch undergoes rigorous testing and carries prestigious international certifications including SGS, ISO, and SDS.
Customized Packaging & Sizes: To support diverse industrial applications, we offer tailored particle sizes and secure packaging options. We support customized iron drum colors (grey, black) and specialized palletizing services (one-layer, two-layer, or three-layer pallets) for safe maritime transit.
Excellent Sealing & Security: Given that calcium carbide reacts violently with moisture, our airtight steel drums guarantee maximum moisture resistance, preventing contamination and ensuring utmost safety during long-distance transportation.

As a leading, factory-direct supplier, our advanced manufacturing base is strategically located close to rich, high-quality raw material resources (such as coke and lime). This strategic advantage allows us to control production costs from the source and guarantee a highly competitive wholesale price for bulk orders. With a robust production capacity exceeding thousands of metric tons per month, we ensure a stable supply chain and zero production downtime for our partners.
Backed by years of expertise in the chemical export industry, we offer efficient logistics networks, comprehensive technical support, real-time order tracking, and regular market trend analysis to help you make informed buying decisions.
