Tooling and Fixtures for Automated Welding

The following are general guidelines to tooling complexity:
• The least complex (and least expensive) has no automation and involves manual clamping with limited dimensional control. This type of tooling typically is a fixture designed to hold a tacked-up assembly with a minimum number of loose pieces that need to be located.

• The most complex (and most expensive) fixturing method is a fully automated tool with complete control of all critical locating points in three dimensions. This tooling may feature part-presence sensing, clamp position control, sequenced clamping, pressure sensing, and more. Generally, all parts comprising the assembly are loose parts with few welded sub assemblies.
• Other welding fixtures fall between these guidelines in both complexity and cost.
• As with any process, simplification is a goal to strive for.
• The more complex the tooling, the more difficult it may be to program the robot to access part weld joints.
• Job shops should encourage customers to use part designs that feature self-locating, simple parts to reduce tooling content.
• Toy tabbing, slot and tab, locating studs, and part interlocking often can be helpful in reducing tooling complexity and cost.
• Some sort of fixturing always is required when a new job is brought into the shop.
• For a one-time part run or a prototype part, angle iron clamped to a stationary or indexing table often is sufficient to locate the parts for robotic welding.
• Considering welders brisbane  automation often means throwing out some traditional ways of working that have been used for years.
• By staying open to exploring new ideas, job shops can find the level of welding automation most suited to their needs.
