Graphite Fixture for Welding Applications
Product Overview
Jincheng graphite fixtures for welding applications are precision-machined graphite jigs and fixtures designed for use in TIG welding, MIG welding, resistance welding, and laser welding operations. These fixtures provide excellent high-temperature resistance and non-stick properties for reliable welding process support.
Our welding fixtures are manufactured from high-density, fine-grain isostatic graphite that withstands the high temperatures and thermal cycling of welding processes. Custom fixture designs and configurations are available to match different welding applications and workpiece geometries.
Key Features
- High temperature resistance up to 3000°C (brief contact with welding arc)
- Non-stick surface to prevent welding spatter from sticking to the fixture
- Good electrical conductivity for resistance welding and grounding applications
- Precision machined for accurate workpiece positioning and alignment
- Easy to machine and modify for custom welding fixture designs
- Custom fixture designs for various welding processes and workpiece types
- Good thermal shock resistance for repeated welding cycles
- Long service life compared to copper or steel fixtures for welding applications

Frequently Asked Questions
Q1: What is the difference between graphite and copper welding fixtures?
A: Graphite fixtures can withstand much higher temperatures than copper, making them ideal for high-amperage welding and arc contact applications. Copper has better thermal conductivity for heat dissipation, but graphite has better non-stick properties for welding spatter.
Q2: Can you manufacture custom welding fixtures based on my workpiece drawings?
A: Yes, we manufacture custom welding fixtures based on your workpiece drawings and welding process requirements. Please provide your workpiece drawings or fixture specifications for quotation.
Q3: How long do graphite welding fixtures last?
A: Fixture life depends on welding current, arc time, and frequency of use. Under typical TIG welding fixture conditions, graphite fixtures last 6-12 months before needing refurbishment.
Q4: Do you offer resistance welding electrode caps and tips?
A: Yes, we manufacture various resistance welding electrodes and electrode caps in different graphite grades for spot welding and projection welding applications.
