Welding Fixtures: Function and Durability to Stand the Test of Time

Welding fixtures and jigs have been at the core of the Cobb TooL service offering since 1988. Our expert team produces fixtures that are tailored to your product design, helping you meet your production needs with precise, streamlined and efficient results.

Quality Fixtures Reduce Cost/Improve Production

Top quality, well-designed welding fixtures are an investment that will reduce your costs, improve your assembly quality and be durable enough to withstand the longtime rigors of a continuous welding environment.

We design and build a full spectrum of welding fixtures – from the simplest sub-assembly fit and tack fixtures to multi-step pneumatic and hydraulic clamping fixtures for the highest quality, highest volume precision parts. Our engineering teams design both manual and multi-step robotic welding fixtures to solve your production and assembly challenges.

We have a proven track record with repeat customers from across the automotive, trucking, agriculture, construction equipment, all-terrain vehicle (ATV), and lawn and garden equipment industries.

Durable Fixtures Designed to Meet Customer Specs

Key to our design process is customer involvement. Once we get an order, we develop a fixture concept that meets your expectations. We typically achieve this through two to three concept review meetings with you, our customer. These can be in-person or online, but they are essential to assure that you receive the welding fixtures you need. We are expert tool designers, but you are the expert on your parts and processes. We’re more successful when we work together as a team.

Design to Maximize Productivity

By our standards, a properly designed and built welding fixture will increase your productivity, improve the quality of your parts, and be durable enough to last — ultimately paying for themselves many times over. We work first to evaluate the goals and considerations of your design challenge – understanding the type of welding fixtures or jigs required for your unique application. We work with you to understand:

  • Production Volume – the number of parts you need to produce each day and the number of welders or robots you intend to use to achieve that goal
  • Type of Weld Fixtures Required – manual clamp, manual welding fixtures; manual fit and tack fixtures with robotic weldout fixture; or fully robotic systems starting with loose parts, utilizing pneumatic or hydraulic clamping; and producing a finished assembly in a single or multi-step process
  • Cost Implications – simplifying the production process to maximize production time and cost efficiency
  • Product Knowledge – understanding your product’s lifecycle and type – from lightweight precision stamping to heavy burnt plate, and everything in between
  • Workforce Skill/Availability – recognizing that better tooling allows more flexibility in welder skill
  • Part Tolerances – manual fit and tack fixtures can allow a skilled welder to compensate for inconsistent component parts. In contrast, robotic welders need the weld joint to be in the same place with little or no gap every time.  Repeatable precision tooling and consistent component parts are essential for successful robotic implementation.
  • Efficiency – creating fixtures that will minimize your production time and cost

Welding Fixture Types/Characteristics

 

Manual Clamp, Manual Weld Sub-Assembly and Separate Final Assembly Fixtures

Characteristics

  • Inexpensive
  • Simplest to design and use
  • Good for low-volume assemblies or large heavy parts
  • Allows welders to compensate for imperfect parts
  • Enables strategic tack welds to prevent distortion during final weldout
  • Often used at the start of large, complex assemblies, followed by robotic finish welding

Pneumatic/Hydraulic Clamp

Characteristics

  • Typically used in a robotic welding application
  • Best for high-volume production needs
  • Pneumatic is appropriate for lighter gauge precision parts
  • Hydraulic is sometimes required for heavy components
  • Cost justified by volume output

Robotic Weldout Tooling

Characteristics

  • Simple, open fixtures
  • Provides easy access to all weld joints
  • Usually requires a series of sub-assemblies in advance of final assembly
  • Excellent for final stages of assembly process
  • Accommodates tack-welded, sub- or final assemblies
  • Maximizes robotic welder utilization

Hand-Applied & Pickoff Jigs

Characteristics

  • Simple
  • Excellent to add small parts after major component assembly
  • Reduces complexity of main assembly fixture
