[Information] Set menu service for reliability testing, haze measurement, and IR analysis.
Before and after the constant temperature and humidity test, haze value measurements and IR analysis can reveal the material's characteristics and changes in molecular structure!
We would like to introduce the "Reliability Testing, Haze Measurement, and IR Analysis Set Menu Service." Plastic (resin) materials can discolor and deteriorate depending on the usage environment. Transparent materials have valuable characteristics such as transparency and high transmittance, but these properties can decline due to degradation, resulting in a loss of functionality as a material. This document explains "Examples of Reliability Testing Equipment," "Haze Measurement Results," and "IR Analysis Results" using tables and graphs. We encourage you to read it.

Detailed information
-
(Figure 1) The grooves are classified based on the shape of the cross-section of the weld. They are generally compared to letters of the alphabet. Examples include I-shape, V-shape, L-shape, K-shape, J-shape, X-shape, U-shape, double-sided J-shape, and H (double-sided U) shape, among others.

This is a detailed example of the most common V-shaped notch.

SU joint When butt welding components with a thickness of less than 4 mm, as in the case of SU pipe joints, an I-shaped groove with a flat end and no angle is used. Normally, filler material (filler metal) is used, but in this case, welding is performed without filler (without filler material), relying solely on melting the base material with the electrode.
