Accumulation of weld slag, spatter, resin, smoke, oil, and dampening adhesive on manufacturing equipment can lead to misalignments and interfere with the proper firing of proximity switches. This can result in the robot halting welding operations or carrying out incorrect welds, leading to scrap generation, equipment breakdowns, and production stoppages. The “No contact” dry ice blast cleaning method offers an efficient and cost-effective solution for removing slag and spatter build-up.
While dry ice blasting does not solve every maintenance solution for welding operations, and at low pressure it loses some effectiveness, it has many benefits for welding operation. Using portable air compressors at above 175PSI, it can really make a difference in cleaning the weld systems.
Some of the benefits include:
Automated Welding Systems
Automated weld lines benefit from dry ice blasting because it is non-conductive and non-abrasive, allowing for the safe cleaning of electrical and sensitive components.
• Robotic Components: Robot joints, arms, and transfer cases are cleaned to maintain mobility and prevent joint failure.
• Fixtures and Jigs: Shuttle jigs, trunnions, and intricate weld cell fixtures are cleared of slag and spatter in their “nooks and crannies”.
• Sensors and Electronics: Proximity switches, photo eyes, electrical control panels, and wiring are safely cleaned without risk of short-circuiting or moisture damage. Remember to lower pressure and ice flow rates around sensitive equipment.
• Conveyance Systems: Diamond plates, shuttle tables, and conveyor chains are treated to remove oil and debris that can cause misalignments.
Manual and Small-Scale Tools
The process is effective for various hand tools and ancillary equipment that accumulate soot and resin.
• Welding Torches and Nozzles: Smaller nozzles can be polished to remove buildup without causing scratches or blemishes.
• Handheld Maintenance Tools: Files, grinders, and levels that collect heavy residue can be cleaned quickly.
• Weld Tables: Large metal surfaces are cleared of weld splatter and slag to ensure a flat, stable work surface.
Ancillary Production Equipment
• Electrical Equipment: Motors, generators, and transformers within the weld cell environment can be cleaned online without cooling or disassembly.
• Pneumatic Systems: Valves and lines that may be compromised by dampering adhesives or grease are cleared to ensure consistent air pressure.
