Joining Solutions. How Do They Compare?

October 01. 2019 | Joining Solutions

If your application is frequently exposed to atmospheric elements such as temperature fluctuations, vibration and corrosion, read on for our comparison of some of the most popular joining solutions. 

1.    Welding

Welding has been used to join metals since the Bronze and Iron Ages. It involves applying high heat to melt 2 or more materials together at specific spots and cooling to form a fused compound. Welding creates a very strong and durable joint when used in the right environment. 

Points to consider

  • It can only be used when the materials are similar. It can’t be used to fuse metal and plastic for example
  • It’s best used on rigid materials. It won’t work well to fuse a malleable material to a rigid material.
  • Constant exposure to temperature variations and vibration weaken the joints due to continued expansion and contraction

2.    Pinch Ear Clamps

Points to consider

  • The clamp is only as strong as the raised point. Any impact to this part can weaken or loosen the clamp.
  • Diameter reduction is very low, different sizes of clamps are needed for different applications resulting in multiple SKUs
  • The thinner the clamp material the lower the tensile strength

3.    Worm Gear Clamps

Points to consider

  • The clamps are usually slotted, which reduces the tensile strength
  • Heat and vibration can cause the screw threading to expand, thereby loosening with time

4.    Bolt Clamps

Points to consider

  • Diameter reduction is minimal, different sizes of clamps are needed for different applications
  • Heat and vibration cause the screw threading to expand and contract which causes loosening with time
  • Does not conform to non-circular materials

5.    Tie-Lok Ties

BAND-IT’s Tie-Lok ties are the premier choice when the application is critical with a high cost of failure. It offers a unique dimple lock with a smooth ID and a low profile, for fast, consistent and reliable clamping tension. 

Points to consider

  • Extreme diameter reduction allows one clamp to be used for different application sizes. 
  • They expand and contract with the material being clamped making them resistant to temperature variations
  • They can be used to clamp both rigid and malleable material in the same joint
  • Forms a low profile single wrapped assembly if space is a factor
  • Available in 304 and 316 Stainless Steel to provide resistance in extreme environments
