Problem Description

The challenge the customer was facing

Premature wear of each star tip attacked the impact area of the tip head with high hardness materials. Together, the user and WAAR agreed to seek a solution to minimize the wear that also came with changing them, resulting in frequent repairs and monthly plant shutdowns. WAAR proposes a solution by applying its 3D-CARB system; Ternium agrees to test it, and 9 star tips are purchased, which are placed in the most delicate positions 6-7 and 8. Over time, a significant improvement is observed.

Welding Alloys Solution

How WA solved the challenge

WELDING ALLOYS ARGENTINA provided a solution to the problem by building on a material of ASTM-36 mild steel with its application called 3 D-CARB, contributing its HARDFACE CNV-O tubular wires in Ø 2.4 / 3.2 mm. Liquid pools were made with this material and once poured, filler was applied over the entire surface of the tillage tool. With this system and the quality of the wires, it solved a problem of utmost importance for operational continuity. Since the year 2000, Ternium-Siderar has been continuously purchasing a complete set of 36 pieces from WAARG.
