This multifunctional hi-lo welding gauge is purpose-built for comprehensive weld quality assessment, capable of measuring bevel angle, weld width, reinforcement height, and joint misalignment with high reliability. The gauge is forged from premium stainless steel, featuring a corrosion-resistant finish and solid structural integrity. Its rugged design is engineered for long-term, high-frequency use, making it a trusted tool across industries such as shipbuilding, pipeline welding, and structural steel fabrication.
Adjustable for Accuracy, Built for Stability
- The SISCO high-low gauge features a tightening nut for adjustable tension control. Once set to the desired level, the measuring parts remain firmly in place, ensuring stable and consistent measurements during operation.
- The entire weld gauge is constructed from high-quality stainless steel, offering superior corrosion resistance. This makes it ideal for use in demanding environments such as marine, industrial, or oil and gas applications.
Precision Markings, Seamless Unit Conversion
- Laser-etched scale lines of our weld gauge are ultra-fine and legible, allowing easy reading in various conditions. This enhances work efficiency and measurement accuracy during field inspections.
- Designed with dual-unit functionality, the high-low gauge allows quick switching between metric and imperial units without the need for manual conversions.
Applications
Weld gauges are widely used in various industries. In boiler manufacturing, they measure weld reinforcement, width, misalignment, and undercut depth to meet pressure part standards. In shipbuilding, they check fillet weld size, leg height, and assembly gaps to ensure hull strength. In oil pipelines, welding gauges assess groove angles and gap sizes to prevent welding defects and leaks. In industrial construction—such as bridges and pressure vessels—they provide accurate weld dimension data for process evaluation and quality control.

Details
Q1: What can the SISCO high-low gauge measure?
A1: The SISCO hi-lo welding gauge is designed to measure multiple critical weld parameters, including bevel angle, internal misalignment (hi-lo), weld height, and gap width. It’s a versatile inspection tool widely used in high-precision welding fields like boiler fabrication, pressure vessels, and pipeline construction.
Q2: Is the gauge suitable for both metric and imperial measurements?
A2: Yes. This welding gauge supports dual-scale measurement, allowing users to switch between metric (mm) and imperial (inch) units easily. This flexibility makes it especially useful in international projects where both systems may be in use.
Q3: How durable is the hi-lo gauge for industrial use?
A3: Crafted from high-strength stainless steel, the gauge offers excellent corrosion resistance and structural stability, even in harsh environments such as offshore platforms or chemical plants. The laser-engraved scale also ensures long-lasting readability under oil, dust, or strong light.
Tips: How do I ensure consistent measurement accuracy in different work environments?
To maintain reliable and accurate readings, always check the tightness of the locking screw before measurement—this keeps the scale stable during use. Additionally, make sure to clean the gauge regularly, especially when working in oily, dusty, or humid environments, to prevent residue buildup from affecting the laser-etched scale clarity. Store it in the included protective case to avoid physical damage between uses.
