不銹鋼焊接發黑難清洗？多槽手動超聲波清洗機來助力

　　Is stainless steel welding blackened and difficult to clean? Multi slot manual ultrasonic cleaning machine to assist

　　在不銹鋼加工行業，焊接是常見的生產環節，但焊接后工件表面形成的發黑氧化皮、焊渣和油污，一直是清洗的大難題。不少廠家用傳統的酸洗、人工擦拭方式清洗，不僅效率低、清洗不徹底，還容易損傷工件表面，甚至污染環境。其實，選對設備就能輕松解決這個問題——多槽手動超聲波清洗機，憑借多槽分工協作的優勢，能實現不銹鋼焊接發黑的高效、精準清洗，今天就專門給大家科普這款設備的核心優勢和使用要點。

　　In the stainless steel processing industry, welding is a common production process, but the formation of black oxide scale, welding slag, and oil stains on the surface of the workpiece after welding has always been a major cleaning problem. Many factories use traditional acid washing and manual wiping methods for cleaning, which not only have low efficiency and incomplete cleaning, but also easily damage the surface of the workpiece and even pollute the environment. In fact, choosing the right equipment can easily solve this problem - the multi slot manual ultrasonic cleaning machine, with the advantage of multi slot division of labor and cooperation, can achieve efficient and precise cleaning of stainless steel welding blackening. Today, we will specifically explain the core advantages and usage points of this equipment to everyone.

　　先說說為啥傳統清洗方式搞不定不銹鋼焊接發黑。不銹鋼焊接時，高溫會讓工件表面形成一層致密的發黑氧化皮，這層氧化皮附著力極強，普通的擦拭或單槽清洗很難徹底剝離。傳統酸洗雖然能去除氧化皮，但化學藥劑會腐蝕不銹鋼表面，影響工件精度和外觀，還會產生大量有害廢液，處理成本高且不符合環保要求。而人工清洗不僅耗時耗力，對于工件的縫隙、焊縫等死角，根本無法清洗到位，殘留的發黑痕跡會影響后續的電鍍、噴涂等工序。

　　Let's first explain why traditional cleaning methods cannot achieve blackening of stainless steel welding. When welding stainless steel, high temperatures can form a dense layer of black oxide on the surface of the workpiece, which has strong adhesion and is difficult to completely peel off with ordinary wiping or single groove cleaning. Although traditional acid washing can remove oxide scale, chemical agents can corrode the surface of stainless steel, affecting the accuracy and appearance of the workpiece, and producing a large amount of harmful waste liquid. The treatment cost is high and does not meet environmental requirements. However, manual cleaning is not only time-consuming and labor-intensive, but also unable to thoroughly clean the gaps, welds, and other dead corners of the workpiece. The residual blackening marks will affect subsequent electroplating, spraying, and other processes.

　　多槽手動超聲波清洗機之所以能高效解決這個問題，核心在于“多槽分工、階梯式清洗”的設計。這類設備通常配有3-5個清洗槽，每個槽承擔不同的功能，從預洗到精洗逐步推進，能徹底去除焊接發黑和雜質。比如常見的三槽機型，第一槽是預洗槽，用清水或堿性清洗劑初步剝離表面浮渣和部分油污；第二槽是主洗槽，采用高頻超聲波配合專用清洗液，精準沖擊焊縫、縫隙等死角，快速剝離頑固的發黑氧化皮；第三槽是漂洗槽，用純水徹底沖洗殘留的清洗劑，避免工件表面出現水印或污漬殘留。

　　The reason why the multi slot manual ultrasonic cleaning machine can efficiently solve this problem lies in the design of "multi slot division of labor and stepped cleaning". This type of equipment is usually equipped with 3-5 cleaning tanks, each with different functions, gradually advancing from pre washing to fine washing, which can completely remove welding blackening and impurities. For example, in common three slot models, the first slot is a pre wash slot, which uses clean water or alkaline cleaning agents to preliminarily peel off surface scum and some oil stains; The second tank is the main washing tank, which uses high-frequency ultrasonic waves combined with specialized cleaning solution to accurately impact blind spots such as welds and gaps, quickly peeling off stubborn black oxide skin; The third tank is a rinse tank, which thoroughly washes away residual cleaning agents with pure water to prevent watermarks or stains from remaining on the surface of the workpiece.

　　和單槽清洗機相比，多槽手動機型還有兩個突出優勢。一是清洗效果更穩定，階梯式清洗能避免前序清洗的雜質污染后續工序，確保每個工件的清洗質量一致，不會出現有的洗干凈、有的殘留發黑的情況；二是更節省成本，各槽清洗劑可針對性調配，主洗槽用高濃度專用液，漂洗槽用純水，比單槽全用高濃度藥劑更節省耗材，同時廢液排放量也更少，環保壓力更小。而且手動操作模式靈活，適合小批量、多品種的不銹鋼工件清洗，不用像全自動機型那樣投入高額成本，性價比更高。

　　Compared with single slot cleaning machines, multi slot manual models have two outstanding advantages. Firstly, the cleaning effect is more stable. Step by step cleaning can avoid impurities from previous cleaning contaminating subsequent processes, ensuring consistent cleaning quality for each workpiece and avoiding situations where some parts are cleaned thoroughly while others remain blackened; Secondly, it is more cost-effective. The cleaning agents for each tank can be adjusted accordingly. The main washing tank uses high concentration specialized solution, and the rinsing tank uses pure water, which saves more consumables than using high concentration agents for a single tank. At the same time, the amount of waste liquid discharged is also less, and the environmental pressure is lower. Moreover, the manual operation mode is flexible and suitable for cleaning small batches and multiple varieties of stainless steel workpieces, without the need for high costs like fully automatic models, making it more cost-effective.

　　給大家說說使用多槽手動超聲波清洗機清洗不銹鋼焊接發黑的關鍵流程，操作起來很簡單。第一步，將焊接后的不銹鋼工件放入預洗槽，浸泡5-10分鐘，讓表面的浮渣和油污初步軟化脫落；第二步，把工件轉移到主洗槽，開啟超聲波，根據發黑程度調整功率和清洗時間，一般10-20分鐘就能徹底剝離氧化皮；第三步，將工件放入漂洗槽，用流動純水沖洗2-3分鐘，確保清洗劑殘留完全去除；最后取出工件晾干或烘干即可。整個過程操作便捷，普通工人經過簡單培訓就能上手。

　　Let me explain the key process of using a multi slot manual ultrasonic cleaning machine to clean stainless steel welding blackening. The operation is very simple. The first step is to place the welded stainless steel workpiece into a pre washing tank and soak it for 5-10 minutes to allow the surface floating slag and oil stains to soften and peel off initially; The second step is to transfer the workpiece to the main washing tank, turn on ultrasonic waves, adjust the power and cleaning time according to the degree of blackening, and generally it takes 10-20 minutes to completely peel off the oxide skin; Step three, place the workpiece into the rinse tank and rinse with flowing pure water for 2-3 minutes to ensure complete removal of cleaning agent residue; Finally, take out the workpiece and air dry or dry it. The entire process is easy to operate, and ordinary workers can get started with it after simple training.

　　選多槽手動超聲波清洗機時，有兩個實用要點要注意。一是看槽體材質和尺寸，優先選304不銹鋼材質的槽體，耐腐蝕、使用壽命長，槽體尺寸要匹配自家工件的大小，避免因工件過大無法完全浸入清洗液；二是看超聲波頻率和功率，清洗不銹鋼焊接發黑，建議選28-40kHz的頻率，功率根據槽體容量選擇，確保超聲能量能均勻覆蓋工件表面，尤其是焊縫等死角。另外，可根據清洗需求選擇帶加熱功能的機型，加熱能提升清洗液的活性，讓發黑氧化皮更容易剝離。

　　When choosing a multi slot manual ultrasonic cleaning machine, there are two practical points to pay attention to. Firstly, it is important to consider the material and size of the tank body. It is recommended to choose tanks made of 304 stainless steel, which are corrosion-resistant and have a long service life. The size of the tank body should match the size of the workpiece to avoid the workpiece being too large to fully immerse in the cleaning solution; The second is to check the ultrasonic frequency and power. For cleaning stainless steel welding blackening, it is recommended to choose a frequency of 28-40kHz, and the power should be selected according to the tank capacity to ensure that the ultrasonic energy can evenly cover the surface of the workpiece, especially in blind spots such as welds. In addition, models with heating function can be selected according to cleaning needs. Heating can enhance the activity of the cleaning solution, making it easier to peel off the blackened oxide skin.

　　總結下來，不銹鋼焊接發黑清洗不用再依賴傳統的酸洗和人工擦拭，多槽手動超聲波清洗機憑借“多槽分工、階梯式清洗”的優勢，能實現高效、精準、環保的清洗效果，還能節省耗材和人工成本。對于小批量、多品種的不銹鋼加工廠家來說，這款設備是解決焊接發黑清洗難題的理想選擇。如果大家不確定自家工件該選哪種規格的機型，建議帶著工件樣品找廠家做試洗，根據試洗效果再做決定，確保設備能精準匹配清洗需求。

　　In summary, the blackening cleaning of stainless steel welding no longer relies on traditional pickling and manual wiping. With the advantages of "multi slot division of labor and stepped cleaning", the multi slot manual ultrasonic cleaning machine can achieve efficient, precise, and environmentally friendly cleaning effects, while also saving consumables and labor costs. For small batch and multi variety stainless steel processing manufacturers, this equipment is an ideal choice to solve the problem of welding blackening and cleaning. If you are unsure which specification of machine to choose for your own workpiece, it is recommended to bring a sample of the workpiece to the manufacturer for a trial wash. Based on the results of the trial wash, make a decision to ensure that the equipment can accurately match the cleaning needs.
