WELDING CONSUMABLES A Lincoln Electric Company

WORLDWIDE WELDING CONSUMABLES FOR HIGH INTEGRITY APPLICATIONS - Power Generation A L - Nuclear Industry - Petrochemical Industry - Offshore Industry

INTRODUCTION TO METRODE 1. The company Metrode was founded in 1963 as a privately owned company. In the subsequent years it has grown to become the UK's leading manufacturer and supplier of alloyed welding consumables. The Company is particularly strong in those industries which require the highest integrity from their welding consumables, such as power generation, chemical and petrochemical, offshore oil and gas, LNG and nuclear. In the two last decades, the export market has been vigorously developed and Metrode has markets globally. It also has an extensive overseas network of distributors...

9. Technical support Technical support is available to help with any aspect of consumable choice, applications or procedural guidance. Field based staff can advise on procedural aspects and factors needed to achieve optimum performance. Facilities are available at Metrode as well as large numbers of other Lincoln facilities worldwide for demonstration, training and evaluation for all the major welding processes which utilise Metrode consumables. 10. Specifications and certification Metrode consumables are manufactured to conform with the current issues of BS EN, BS EN ISO or AWS-ASME standards...

DATA SHEETS : INTRODUCTION AND EXPLANATORY NOTES The individual data sheets collect all of the processes (MMA, TIG, MIG, SAW and FCAW) onto a single data sheet, allowing all products for any alloy type – eg 316L – to be seen at a glance. The front page of each data sheet provides the generic information on that particular alloy – alloy type, materials to be welded, applications, microstructure, welding guidelines, PWHT, additional information and products available. The data specific to the individual products – product description, specifications, analysis, mechanical properties etc – are then...

DATA SHEETS: INTRODUCTION AND EXPLANATORY NOTES All-weld mechanical properties Minimum and typical tensile and impact properties are given where applicable to satisfy national specifications or material requirements. Caution is generally advised in translating these all-weld (longitudinal) values to joint (transverse) test values. Operating parameters Current ranges are based on satisfactory fusion and arc stability. Optimum conditions are influenced by variables such as welding position, base material thickness, and heat input considerations, etc. Most electrodes operate smoothly on DC+ (positive...

Section A : Low Alloy Steels METRODE PRODUCTS LTD HANWORTH LANE, CHERTSEY SURREY, KT16 9LL, UK Tel: +44[0]1932 566721 / Fax: +44[0]1932 565168 Email: [email protected] Website: www.metrode.com This section includes consumables suitable for welding general engineering and structural steels, from medium tensile grain-refined CMn and semi-cryogenic steels (approximately -75°C) to specialised heat and creep-resistant CrMo types reaching the threshold of stainlessness at 12%Cr. Flux coverings of all electrodes are of all-positional basic low-hydrogen type and employ binders giving high resistance to...

Datasheet Alloy Process Product AWS Classifications EN / EN ISO Classifications Cr-Mo creep resisting consumables mainly for the power generation industry [continued] LOW ALLOY STEELS E CrMoWV 12 1 B W CrMoWV12 1 High toughness 1-3%Ni consumables for applications from -40°C down to about -75°C Consumables for high strength low alloy steels requiring tensile strengths from 620MPa up to 825MPa Consumables for copper containing weathering steels eg. Corten Electrode for the joining of rail steels using a slag-over-slag technique

ALLOY TYPE Nominal 0.5% Mo alloying results in improved elevated temperature performance over that of CMn steels. Used for the fabrication of vessels and associated pipework demanding creep rupture strength and ductility at temperatures up to about 450°C. The Mo content also enhances resistance to hydrogen attack in chemical process plant operation. Favourable mechanical properties of both as-welded and stress-relieved weld metal are also useful in welding structural and general engineering steels for ambient or sub-zero temperature service. In this respect these consumables are related to the...

Mo.BMOLYBDENUM ALLOYED MMA ELECTRODE FOR ELEVATED TEMPERATURE SERVICE PRODUCT DESCRIPTION Basic flux, metal powder type coating on high purity mild steel core wire. Moisture resistant coating giving very low weld metal hydrogen levels. Recovery is about 120% with respect to core wire, 65% with respect to whole electrode.
