ESAB introduces the OK AristoRod ® 38 Zn to minimise porosity

AristoRod 38 Zn allows the zinc vapour to escape. It addresses the root cause of porosity and spatter associated with standard ER70S-6 wires without the expense of burn through associated with metal cored wires,” said Jose Abal-Lopez, global product manager non and low alloyed solid wires, ESAB. “ESAB conducted head-to-head tests against other common options for welding galvanised steel. The results were conclusive: OK AristoRod 38 Zn offers the best performance.” OK AristoRod 38 Zn is available in diameters of 0.8, 1 and 1.2mm in 18kg spools and 250kg Marathon Pacs.

ESAB Welding & Cutting Products has launched a solid wire with a specially alloyed formula that minimises porosity and spatter on galvanised steels. The OK AristoRod ® 38 Zn has been designed to reduce or eliminate rejects and rework, delivering optimised results when welding the galvanised steel components used in transportation, white goods, agricultural tanks and troughs, HVAC systems and construction (roofs, facades, gates, fences, stairs and catwalks). “Through controlled micro-alloying elements in its formulation, OK

also been sold to produce aluminium welded pipe and profile. The quality of the products combined with the continuous research and improvement of new solutions has allowed Elestar to weld ferritic and austenitic stainless steel tubes, copper and brass. Using the SiC technology for several years has allowed Elestar to design small cabinets that can also be used in a small space. Elestar induction generators are designed to withstand harsh environ-

Elestar IHT, a specialist in induction heating since 1995, manufactures and installs systems for longitudinal welding of steel pipes, using HFI SiC MOSFET technology (silicon carbide transistors). The company recently installed a Welder SiC generator for contact welding of conical steel poles, used for street lighting. This is the first of an order of three Welder SiCs and three induction heaters, to keep the poles straight. Another five Welder SiC models have

In addition to induction welding generators, Elestar produces in-line induction heating systems for any grade of stainless steel tubes (bright annealing), ranging from 30 to 600kW. Elestar Srl www.elestar.it Easy butt fusion machine setup application

A detailed report at the end of each weld provides technical data with exact graphs and parameters to compare against international welding standards and a geolocation map. The welding reports can be shared in pdf format via email and WhatsApp, or saved to a phone or on a cloud archive. Ritmo SpA www.ritmo.it

welding standards (ISO, DVS, UNI, ASTM, etc), pipe diameter and SDR. The GPS and smartphone scanner allows collection, transfer and storage of information by project name. The exact location of each pipe weld can be recorded, as well as the construction site. Pipe and fitting barcodes and operator badge can be scanned, and a photo can be taken before and after the installation.

Set & Go Pro is a professional application for Android smartphones and tablets that provides a new way to work with Ritmo Easy Life butt fusion machines. It combines ease of use and innovation with the advantages of a CNC welding system, eliminating the expensive hardware of data logging. The Easy Life welding machine is set up using a smartphone or tablet with a few easy steps: choose the international
