Solution Overview

Problem

Welders face difficulties in selecting the proper welding consumable due to unknown base metal composition and available consumable information, affecting the strength and durability of welds.

Innovation Solution

A welding electrode selection system that uses a positive metal identification tool to determine base metal composition and communicate it to a power supply controller, which, along with consumable data, predicts resultant weld properties and provides guidance to the user for optimal consumable selection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional welding consumable selection methods are used, then the welding process is simple and quick, but the weld strength and durability cannot be optimized due to unknown base metal composition

Engineering Contradiction:
Improveweld strengthVSAvoidsystem complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The system performs base metal composition analysis and consumable identification before the welding operation begins. The positive metal identification tool analyzes the base metal composition in advance, and the consumable identifier scans the welding consumable to determine its composition. This preliminary information gathering allows the processor to predict weld properties before welding starts, enabling informed consumable selection without adding complexity to the actual welding process.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system introduces a processor as an intermediary between the base metal analysis, consumable identification, and weld property prediction. The processor receives composition data from both the base metal analysis and consumable identification, applies welding metallurgy principles to predict weld properties, and presents recommendations to the operator. This intermediary layer integrates multiple data sources and provides intelligent decision support without requiring the operator to manually analyze complex compositional data.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If base metal composition analysis is performed to ensure proper consumable selection, then weld quality is improved, but the welding process time increases

Engineering Contradiction:
Improveweld qualityVSAvoidprocess time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system replaces traditional mechanical/physical base metal identification methods (such as visual inspection, magnetic particle testing, or metallographic analysis) with positive metal identification technology that uses electromagnetic or spectroscopic principles. This substitution enables rapid, non-destructive composition analysis that provides immediate results, eliminating the time-consuming nature of conventional analysis methods while ensuring accurate base metal identification for proper consumable selection.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Measurement precision

If the welder manually determines base metal composition and selects consumables, then equipment cost is lower, but the accuracy of consumable selection decreases

Engineering Contradiction:
Improvecomposition identification accuracyVSAvoididentification system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system enables self-service identification where the positive metal identification tool automatically analyzes the base metal composition without requiring the operator to manually determine it. Similarly, the consumable identifier automatically scans and identifies the consumable composition. The processor then automatically predicts weld properties and provides consumable recommendations. This automation eliminates human error in composition determination and consumable selection while keeping the interface simple for the operator.

Inventive Principle:
Principle #25Self-service

AI summary

Embodiments of the present invention are directed to systems (100) and methods of predicted a welding property (600) for a given welding operation using at least one electrode. Embodiments determine a predicted weld deposit property and compare the predicted property to a desired property to determine whether or not a selected electrode for the given welding operation can achieve the desired weld deposit.
