接合強度測定用補助具

Auxiliary tool for bonding strength measurement

Abstract

【課題】 蝋付け、溶接、溶着、接着等の方法により接合した試験片の接合面のせん断方向の接合強度を容易かつ正確に測定するための接合強度測定用補助具を提供する。 【解決手段】 平板状試験片同士の一部を重ね合わせて接合した接合強度試験片の引張方向の荷重作用軸のズレを補正する接合強度測定用補助具であって、 少なくとも蓋部及び本体部からなり、該蓋部が下記(1)に示す構成部位であり、該本体部が下記(2)、(3)に示す構成部位を有する、接合強度測定用補助具。 (1)該接合強度試験片の引張方向以外の荷重変形を抑制するための蓋部。 (2)内部に該接合強度試験片の接合面に引張荷重を伝達するための突起部。 (3)外部に該接合強度試験片の引張荷重のズレを補正するための平板状突起部。 【選択図】 なし
PROBLEM TO BE SOLVED: To provide an auxiliary tool for bonding strength measurement, for easily and accurately measuring bonding strength in a shear direction of a bonded surface of a test piece bonded by a method, such as brazing, welding, weld depositing, and bonding.SOLUTION: An auxiliary tool for bonding strength measurement corrects misalignment of a load action axis in a tensile direction of a test piece of bonding strength formed by bonding plate-like test pieces that are partly overlapped with each other, and includes at least a lid portion and a body portion. The lid portion is a component shown in (1) below, and the body portion has components shown in (2) and (3) below. (1) A lid portion preventing deformation under load in a direction other than that in a tensile direction of the test piece of bonding strength. (2) A projection for transmitting a tension load to a bonded surface of the test piece of bonding strength, which is provided inside the auxiliary tool. (3) A plate-like projection for correcting misalignment in a direction of applying a tension load to the test piece of bonding strength, which is provided outside the auxiliary tool.
