    Several design considerations should be taken into account for economical and efficient welding. Many of these apply to other joining methods, and all apply to both subassemblies and the complete assemblies. Recognize and analyze the design problem up front before the work begins: When we quote a job that requires metal joining, our Engineers review blueprint designs to assure that the part will meet and perform well under expected and worst-case conditions. Considerations include:

    What is the most economical method to build the part?
    1. Can the part be made to print?
    2. Is the part designed correctly to yield parts of high integrity?
    3. How, when, and how much should the part be joined {brazed or welded]?
    4. Are there methods that can be suggested for product improvement that consider reduced cost-effective product or process re-design?
    5. Will other joining methods, such as brazing, offer equal or better performance?


    Consider Fit, Form and Function:

    The most elegant design is useless if the parts cannot be made efficiently. Welders or Brazers cannot always fabricate what designers think up. Designers should spend time with the experts and consult our manufacturing engineers during the design stage to become familiar with the challenges of translating drawings into products.

    Our Engineers must not only consider design and material requirements before they quote or process a job; they also have to take the actual brazing or welding processes into account. Because methods and manufacturing procedures affect both braze & weld quality, our engineers must make certain that they the part can be made to print. Variables such as distortion induced by welding must be considered at the unset. The quality of welds is ultimately our responsibility once we accept the job.

    Use jigs, fixtures, and positioners: Jigs and fixtures hold parts in correct alignment for welding. Our designers and manufacturing engineers specify the jigs, fixtures or positioners required. The cost of designing fixtures, creating fixture or jig blueprints, building the tools are all costs that are included in the cost of welding. HTG has engineers that design all tooling for each application which is generally unique.

    Weld Fixtures

    HTG builds its own high quality, cost effective weld fixtures. Our weld fixtures offer solutions that are robust, well designed for the application, and fairly priced. We concentrate our resources towards developing weld fixture solutions for each application.

    Weld Fixture Design

    Welding and Brazing Processes starts with good part and tooling design. HTG has design resources both in-house and longtime partnerships with experienced tool building design contractors. We use Auto Cad, design software.

    Specify welding procedures: Our customers do provide weld specifications and possibly welding procedures. If procedures are provided, our engineers will review all specifications and procedures during our quoting process. Our responsibility is to produce acceptable-quality welds at the lowest overall cost. Once, we receive a Purchase Order we develop Weld Procedures and Weld Schedules for our shop floor personnel to follow. The engineered procedures are tailored to the application and spell out exactly what welds are to be made and how they are to be made. Procedure variables include the brazing and welding processes, conditions, and operation details; joint details; filler metal and shielding gas (if any), and safety.

    Different procedures produce different weld qualities, such as strength only, commercial, or code quality. Strength-only procedures produce the highest welding speeds at the lowest costs. Appearance and quality are not important in these applications. Defects and imperfections are acceptable as long as the welds perform satisfactorily under service conditions. Tests should be specified to confirm performance of strength-only welds.

    Aerospace - quality procedures produce higher quality levels and appearance. Such welds are crack free and pressure tight. They look good and meet joint strength requirements. However, commercial-quality welds may have minor defects. Weld quality is defined in our internal procedures.

    Certified aerospace quality welds must be free of defects and pass nondestructive testing. In practice, this usually means welds that are free of cracks and have limited porosity, undercut, or other flaws.

    Control and correct distortion: During welding, localized heating causes temperature variations, which may cause residual stress and permanent distortion. Our tooling designers must control and correct distortion. One of the best techniques to lessen distortion is restrained assembly, in which jigs or fixtures restrain the parts rigidly so they cannot move. The use of jigs and fixtures reduces distortion, but stress may build up within the joints and may increase the chance of cracking.

    Designers design parts so welds are made near the part's neutral axis, because weld-shrinkage forces away from that axis may cause angular distortion. The presetting assembly method will reduce distortion.Distortion also can be reduced by avoiding over heating the components, as well as by using subassemblies.

    Specify heat treatment: Stress in most welded materials can be relieved by heating them while restraining them in the desired position. The weld materials relax, relieving some of the residual stress. However, the structures must be heated uniformly, and cooling must be slow so that stresses do not redevelop. Stresses in large structures are not easily relieved through heat treatment. Local stress relief is sometimes possible but may be impractical due to the large heat sink afforded by these structures. Stress relief is critical for dimensional stability in parts that will be machined. If structures contain much residual stress, they will move and distort when the machining process begins removing material. HTG has equipment to provide the stress relief operations after welding if required.

    Consider cleaning and inspection: Parts must be clean prior to welding in order to avoid the possibility of bad welds. After welding, Parts may require clean up based on the weld procedures in place. Certain joints are inherently difficult to inspect. Design critical joints so they can be inspected with confidence. For example, fillet welds and spot welds are difficult to inspect. With spot-welding of aerospace products, weld inspection techniques are generally established. Pull or peel testing are common methods of inspection provided by HTG. Full-penetration, butt-joint welds are much easier to inspect by standard methods.

    Our inspection criterion is included in the shop procedures that enable our personnel to know what is required. Our inspectors first examine welds visually. Surface discontinuities give useful information about workmanship are reviewed. We do not produce shoddy-looking welds or welds that contain internal discontinuities. Thus, visual inspection often is followed by more revealing inspection techniques, such as ultrasonic or radiographic testing. This is determined by the specification and procedures that are being followed.

    As an industrial process, the cost of welding plays a crucial role in manufacturing decisions. Many different variables affect the total cost, including equipment cost, labor cost, material cost, and energy cost. For manual welding methods, labor costs generally make up the vast majority of our total cost. As a result, many cost-saving measures are focused on minimizing operation time. To do this, welding procedures with high deposition rates can be selected, and weld parameters can be fine-tuned to increase welding speed. Mechanization and automation are often implemented to reduce labor costs, but this frequently increases the cost of equipment and creates additional setup time. Material costs tend to increase when special properties are required.
