Understanding the Core Fundamentals of Strip Cladding Technology
The strip cladding process
represents a specialized overlay welding technique depositing corrosion-resistant alloys onto base metals. Unlike conventional methods, it employs continuous metal strips ranging from 30mm to 120mm in width as filler material. Key mechanisms involve the formation of a metallurgical bond between the substrate and alloy layer through controlled fusion. Process parameters including voltage (typically 26-34V), amperage (550-1200A), and deposition rates (15-45kg/hr) require precise calibration based on ASME Section IX standards.
Technical Advantages of Electroslag Strip Cladding Technology
Electroslag strip cladding process delivers 60% higher deposition efficiency than submerged arc methods while reducing dilution rates to 10-15%. The submerged molten slag pool creates superior thermal conditions:
- Precise heat control maintains interpass temperatures below 350°F
- Slag chemistry enables hydrogen content below 4ml/100g
- Minimized distortion: 1.2mm/m versus 3.5mm/m in SAW processes
Industrial trials demonstrate 92% reduction in post-weld machining requirements for pressure vessel components, directly translating to 40% cost savings on large-scale projects exceeding 500 sq.m. cladding areas.
