Properly holding pre-tacked assemblies or capturing loose components to be welded is one of the most important keys to success in automated welding. An infinite variety of a weldment’s shape, size, and weight will require unique, custom engineered fixturing solution in every application. Midwest Engineered Systems capability allows for us to design robust fixture for your parts no matter how complicated and deliver a turnkey production line integrated solution.
Automated Welding Fixtures
Automated Weld fixtures do more than just clamp down on metal components. They also locate a number of workpieces to a predetermined acceptable tolerance and generally can be modified to work well within precise dimensions. Using weld fixtures lowers overall production costs and makes the work environment safer for the operator. They can make it easier to rapidly produce welded parts on a regular basis and with consistently high standards of quality for the entire welding process.
Automation with welding fixture systems can eliminate the need for manual welding fixtures and can reduce the necessity of human labor in this part of welding operations.
The main benefits of integrating automation into weld fixture designs include:
• Greater precision in welded components
• Allowing machines to take on physically demanding, hazardous or repetitive tasks
• Robots can go beyond human limitations in terms of load bearing, processing speed, endurance, size of materials and in strict adherence to a set of task directives
Hydraulic Welding Fixtures
Hydraulic welding fixtures use hydraulic fluid to power clamps or gripper to reliably hold machine parts and other metals that will be welded together. Using hydraulics with welding fixtures permits a level of robotic precision and highly-repeatable part positioning that just isn’t possible with manual welding fixtures. Automated hydraulic welding fixtures run stably, are capable of welding without causing metal distortions and allow repeatability to meet customer quality expectations.
Pneumatic Welding Fixtures
Pneumatic welding fixtures work through air-actuated cylinders that provide the holding pressure a fixture uses to clamp the components to be welded down. These types of clamps are well-suited for repetitive, high-production operations. Sealed clamps are the pneumatic welding fixtures of choice for heavy welding jobs that require a high-degree of clamping capability. Pneumatic welding fixtures are used to weld parts in the Food and Packaging, Aerospace and Automotive industries. It also has applications in CNC Machining, Fixturing, Testing and in Welding.
Manual Welding Fixtures
Manual welding fixtures are designed to allow welders to manually handle weld components. Manual welders with the proper training and certification can work with different types of stainless steel, carbon steel and aluminum materials. To maximize efficiency, welding workstations should be ergonomically designed and possess sufficient spacing and other safety features to minimize the chance of workplace accidents or equipment damage. Robotics combined with manual welders can productively split the welding-related labor: automated processes can handle repetitive and/or physically strenuous welding tasks, while manual welders can handle highly specialized tasks. Both types of welding are used in utility-scale racking systems, construction, the automobile industry and in the field of renewable energy.
